Writing is wonderful. Thanks to the generation effect, it helps you better remember what you read – even if it’s just by taking notes – and it’s good for your mental health. Building a writing habit is one of the most powerful things you can do for yourself as a maker.
As Anaïs Nin would say: “We write to taste life twice, in the moment and in retrospect.” Whether you’re trying to make sense of a situation, come up with new ideas, stay consistent with your practices, or reflect on what’s working and what’s not – writing can support you every step of the way.
Taking the time to write slows you down just enough to notice what’s going on in your mind, clarify your thoughts, and explore your curiosity with intention. Over time, it becomes not just a record of what you’ve done, but a mirror for how you think. Writing can support:
Writing doesn’t just clarify what you think – it reinforces how you learn, adapt, and evolve. Whether you’re exploring a new idea or reflecting on a past experience, the act of writing turns vague thoughts into tangible insights you can return to and build upon.
Personal growth doesn’t have to follow a rigid plan. In fact, systematically trying things out – what I call tiny experiments – can be far more sustainable and rewarding. Writing fits perfectly into this kind of experimental practice and can support you at every stage:
1. PACT: Make a pact with yourself grounded in curiosity. You don’t need a detailed plan, just a simple commitment to explore something that feels alive: “I will [action] for [duration].” Writing it down, whether in a journal, a note to a friend, or a public post, gives form to your intention and creates a gentle incentive for showing up and completing the experiment.
2. ACT: It’s easy to focus solely on execution and forget to capture what’s happening. Writing while you carry out your tiny experiment – such as capturing quick notes or logging thoughts as they emerge – can help you stay connected without the pressure to perform.
3. REACT: Once the experiment is complete, reflection is where learning happens. Writing helps you process the experience and make sense of what worked, what didn’t, and what you might want to try next (for example with the Plus Minus Next method).
4. IMPACT: Over time, your tiny experiments might lead to something bigger. Whether you’re building a product, launching a project, or simply sharing what you’ve learned – writing helps you consolidate your insights and share them with others in a generative way.
Writing helps you stay engaged, deepen your learning, and notice the invisible threads that tie your experiments together. It’s a low-cost, high-value companion for personal experimentation.
It changed my life, and I think it can change yours too. So get a notebook, open a new document, or maybe even start a newsletter. Writing won’t do the growing for you, but it will support, shape, and accelerate your growth in countless ways.

You’re working late on a deadline when someone emails about an urgent meeting tomorrow. Within seconds, your body prepares you for action and your cortisol levels rise.
Cortisol isn’t inherently problematic; it’s a sophisticated chemical messenger that helped our ancestors survive countless threats. Yet in today’s environment this evolutionary advantage has become a potential liability.
Beyond the anxiety and sleep disruption, research connects chronic cortisol elevation to memory impairment, immune suppression, and a bunch of metabolic problems. Understanding this connection can help you better manage your cortisol levels to support both your mental and physical wellbeing.
To understand why stress affects us so profoundly, we need to look at how cortisol actually works in the body. The body’s response to stress follows a precise neurobiological pathway.
When the brain perceives a threat – psychological or physical – the hypothalamus activates the HPA axis. This triggers a series of hormonal signals culminating in the adrenal glands releasing cortisol into the bloodstream.
This mechanism is a sophisticated adaptation where cortisol serves several vital functions during acute stress:
This is your brain on cortisol. Then, when the threat passes, baseline cortisol levels are restored and the body returns to homeostasis. These changes are remarkably effective for managing short-term challenges, the acute stressors our physiological systems evolved to handle.
The problems arise not from the cortisol response itself, but from its persistent activation. Our physiology isn’t designed for the prolonged stress that characterizes modern life: the toxic productivity, financial instability, information overload, and social complexity.
Chronic elevation of cortisol creates serious biological consequences: memory and executive functions decline, neuronal structures change, and widespread metabolic problems emerge. These disruptions lead to both mental and physical health challenges.
The good news is that our cortisol response isn’t fixed – it can be modulated through intentional practices. This adaptability gives you an opportunity to improve your cortisol regulation.
While we can’t eliminate stress entirely, we can develop habits that help our bodies process it more effectively. The following strategies can make a significant difference in your cortisol levels, often within just a few weeks of consistent practice:
1. Cognitive reappraisal. How you think about stress actually changes how it affects your body. When you feel your heart racing, try reframing it like this: “My body is helping me rise to this challenge.” This mental shift doesn’t just feel better – research shows it actually changes how your cardiovascular system responds.
2. Strategic recovery. Working non-stop keeps cortisol levels consistently elevated. Instead, try working in focused 60-90 minute blocks followed by short breaks. During these recovery periods, take a brief walk, practice deep breathing, or chat with a colleague. This works with your body’s natural cortisol rhythms instead of fighting against them.
3. Physical activity. Exercise is a powerful cortisol regulator, but intensity matters. Moderate, consistent activity (30-40 minutes, 3-5 times weekly) can help but excessive high-intensity workouts can actually worsen cortisol imbalances. Activities with rhythmic movements – walking, swimming, cycling – are particularly effective at regulating cortisol.
You don’t need to completely eliminate stress – that’s neither possible nor desirable. Instead, aim for a healthier relationship with stress where cortisol serves its proper function without staying elevated for too long.
The most effective approach is personal experimentation. Conduct tiny experiments based on the strategies above for a few weeks, notice which ones make you feel better, and build them into your routine.
And remember: our bodies possess remarkable adaptability when it comes to stress. While evolution created our cortisol response system, your daily habits and thought patterns continuously reshape it.

Humans have co-evolved with environmental changes. Our ancestors synchronized their activities with seasonal cycles – planting, harvesting, and conserving resources according to the season – and our bodies developed physiological responses to these seasonal shifts that persist today.
Around 60% of the global population experiences a distinct spring season each year. The Celtic festival of Beltane, the Hindu celebration of Holi, and the Japanese Hanami traditions all acknowledge the importance of this transitional period.
However, because of modern conveniences and climate-controlled environments, we’ve largely forgotten our connection to these natural rhythms. A simple way to reconnect with this ancestral knowledge and make the most of spring is by conducting springtime experiments.
From an evolutionary perspective, humans developed behavioral adaptations to seasonal changes to optimize survival. Different strategies for acquiring and preserving resources were necessary throughout the year, which progressively became encoded in our physiology.
For early human societies, spring brought increased food availability and social interaction opportunities. This likely selected for heightened exploration during spring months – a way to maximize resource acquisition during this crucial period.
Increased daylight exposure during spring also reduces melatonin production while increasing serotonin levels. These neurochemical shifts correlate with changes in cognitive function, mood, and energy.
And moderate warming might slightly improve performance on tasks requiring cognitive flexibility – which means that springtime temperatures might also help us better “think on our feet”!
Although the research primarily reflects the northern hemisphere experience, the same principles apply during September to November for people living in the southern hemisphere, and tropical regions experience transitions between dry and wet seasons that also trigger increased biological activity.
So, overall, research suggests that transition periods between seasons provide opportunities for behavioral adaptation across cultures and climates. Which means anyone can leverage these shifts to explore new behaviors, new skills, new places, and even new relationships.
Spring offers an ideal period for personal experimentation. Rather than implementing permanent changes, consider trying new things and seeing what works and what doesn’t, framing your personal growth as a series of springtime experiments using these questions as a starting point:
1) “How might I expand my social circle?” Research suggests that shared activities create effective foundations for new connections. Join community-based outdoor activities where interactions occur naturally. Test “social diversification” by introducing different social groups to each other. Experiment with different ice breakers when meeting new people.
2) “How might I engage with my environment differently?” Implement systematic curiosity by noticing one natural element daily – maybe it’s a flower, a tree, a woorden bench you’ve never noticed. Change your indoor environment with elements that connect to seasonal changes, maybe through plants or natural light. Visit new places: parks, museums, or new neighbourhoods. Go to your local market and make food using seasonally available ingredients.
3) “How might I reimagine my routines?” This applies to both your routine behaviors and thought patterns. Study new topics outside your established expertise or work. Practice metacognition by observing your thoughts and emotions. Try that productivity method you’ve been curious about to explore new ways of managing your time and energy, perhaps by better aligning your workflows with your chronotype.
4) “How might I incorporate more sensory experiences into my daily life?” Try going barefoot to test the effects of direct contact with natural surfaces such as grass and soil (I’ve seen this referred to as “earthing”). See how it feels to wear natural fabrics. Make your own candles. Experiment with getting a massage every week. Or massage yourself with different oils and take notes of the massage protocols that seem to help.
5) “How might I experiment with my creative expression?” As a liminal moment of renewal, springtime is great for creativity. Experiment with dancing, painting, drawing, singing, writing. Produce some form of easy creative work each day. Take inspiration from nature by incorporating natural patterns and principles into your creative project.
Consider running some of these experiments with others, and make sure to reflect on the results using the Plus Minus Next template. What worked? What didn’t? What might you want to focus on next? This is what we’ll allow you to create growth loops, where each experimental cycle provides lessons for the next one.
If you’re looking for some inspiration, here’s a short list of tiny experiments that can be particularly interesting to conduct during the spring:
Spring is a perfect time to try new things in your life. Your body naturally responds to the seasonal changes happening around you, giving you a biological boost for personal growth.
And don’t worry if you’re not experiencing spring right now. You can bring this “springtime energy” to your life anytime – approaching each day with more curiosity, openness to new ideas, and a willingness to experiment.
Start small. Choose just one experiment, perhaps from the ideas listed above. Like the first shoots emerging from the soil, your initial attempts might seem modest, but they contain the seeds of significant growth.
Each tiny experiment gives you valuable information about what works for you, progressively creating a unique foundation for your personal development journey. So, what experiment will you try first?

When aerospace engineer Burt Rutan’s team set out to build a private spacecraft on a limited budget, they faced challenges deemed insurmountable without government-scale resources. But they tackled spaceflight differently.
Rather than following the hierarchical approach of traditional aerospace companies, Burt Rutan created a culture where experimental data, not authority or lengthy theoretical debates, drove decisions. This experimental mindset ultimately led his team to win the $10-million Ansari X Prize with SpaceShipOne, revolutionizing private spaceflight.
Traditional leadership models that rely on certainty and control are increasingly ineffective. The complexity and pace of our modern world demand a kind of different leadership, one that embraces uncertainty rather than fighting against it.
Leading like a scientist begins with a fundamentally different relationship with uncertainty. While leaders traditionally view uncertainty as a threat, research shows that teams that openly acknowledge what they don’t know consistently outperform those projecting false confidence.
An experimental mindset means approaching problems with curiosity rather than anxiety. When faced with unexpected results, scientists don’t rush to blame someone or hide the outcome. Instead, they lean in with genuine interest: “That’s interesting… what can we learn from this?”
Similarly, this mindset can transform how we collaborate. It creates environments where people actually test their assumptions and engage in what researchers call humble inquiry – asking genuine questions rather than providing ready-made answers. Their research suggests that when we lead with questions instead of solutions, critical information surfaces more readily.
However, for this to work, it requires updating our definition of success from achieving a desired outcome to learning something new. This perspective transforms the paralyzing fear of being wrong into an intellectual adventure, where uncertainty is a doorway to insights that linear goals might have never revealed.
You don’t need a laboratory to lead like a scientist. An experimental mindset can be applied in any context where uncertainty exists – which, in today’s world, is virtually everywhere. Below are three simple practices to incorporate into your leadership.
Leadership in the face of uncertainty isn’t about having all the answers. It’s about asking better questions and designing tiny experiments to find the answers. By adopting an experimental mindset, we can transform uncertainty from a source of anxiety into a springboard for discovery.
So, the next time you face a challenge without a clear path forward, ask yourself: “What would a scientist do?” This will likely involve curiosity, experimentation, collaboration, and being comfortable with not knowing… yet!

A month ago, my book Tiny Experiments finally made its way into the world after years of work. Launch day brought a flurry of notifications and messages of support, along with that strange feeling of seeing something that existed only in my mind now in other people’s hands.
There’s something surreal about thousands of hours of work culminating in a single moment.
As I write these words, I can feel the first signs of what I’ve come to call the “comedown effect” – the psychological recalibration that occurs after a major achievement, when your brain transitions from the intensity of doing to the quieter state of done.
Although it’s a natural readjustment, this comedown can feel disorienting even in the midst of success.
The comedown effect is largely driven by our brain’s dopamine system, which regulates motivation and reward processing. Contrary to popular belief, dopamine isn’t primarily about pleasure but about anticipation.
Research shows that dopamine neurons respond most strongly to unexpected rewards. However, once rewards become expected (which is the case once we’ve completed a big project), these same neurons decrease their firing rate, creating a neurochemical environment that can feel like emotional withdrawal.
That’s why many of us experience what feels like a “post-completion void” – that hollow space that opens up when the work that once shaped our days and thoughts is suddenly complete.
Public achievements add another layer to the comedown effect. When our work becomes visible to others, we might start measuring its value through external validation. That social media post celebrating your launch might feel great when the likes roll in, but empty a day later, making you seek more dopamine hits to relive that initial high.
So, how can you land more softly after achieving something big?
The comedown effect is a normal part of creating and achieving. We can’t avoid it completely, but we can learn to handle it better. Here are five strategies to manage this natural post-achievement emotional recalibration.
Humans are wired for exploration. That’s why we derive more lasting satisfaction from the journey than from the attainment. That’s also why each big milestone is better thought of as a marker along your own unique path and not as a final destination.
The comedown effect is a natural reset that prepares us for our next creative season. It returns us to the open-endedness of curiosity, meaning-making, and lifelong learning.
Once we understand how it works, we can meet our achievements with a kind of dual awareness: celebrating the summit while remembering that an experimental life is made of both ascents and descents, forming growth loops that are sometimes uncomfortable, but always generative.

It’s spring, and once again we’re being bombarded with advice about spending time in nature. Yes, there are many studies showing the positive impact immersion in nature can have on your mental health. For example, research shows that walking for 90 minutes in a natural setting will lower the activity in your prefrontal cortex, a brain region that is active during rumination.
But this well-meaning advice it’s not always practical. Not everyone has easy access to parks or forests – some of us live in cities, work long hours indoors, have mobility challenges, or can’t afford weekend getaways. How can we go about getting these benefits when living in an urban environment?
A great way to manage your mental health is to learn how to “move outside of yourself.” This is when you focus on simply being present in the moment, as opposed to projecting yourself into the future or ruminating about the past. Some of the most effective methods to reach this state of grounded awareness are meditation and mindfulness practices.
Being immersed in nature is another way to reach this state. But not everyone lives in an area where this is possible or can afford to regularly travel to the countryside. Most people reading this will actually be living in a medium to big city.
This is why the research paper I’m going to tell you about made me so happy. In this two-week study, the researchers divided people into three groups:
While the “business-as-usual” group just went on their daily lives without any particular instructions, participants in the “nature” and “human-built” groups were asked to pay attention to how natural or human-built objects in their everyday surroundings made them feel, take a photo of the objects or scenes that evoked emotion in them, and to provide a description of emotions evoked.
As you may have guessed, the participants in the “nature” group showcased significantly higher levels of happiness, defined by their sense of elevation and how connected to other people they felt.
But what makes this study so interesting is the definition of “nature” the researchers used. This could be anything that was not human-made: a houseplant, a bird, a dandelion growing in a crack in a sidewalk, or even just sun through a window.
“This wasn’t about spending hours outdoors or going for long walks in the wilderness. This is about the tree at a bus stop in the middle of a city and the positive effect that one tree can have on people,” explained positive psychology researcher Holli-Anne Passmore.
This study is fascinating because it’s so applicable to our daily lives. It shows that it’s all about being proactive with our mindfulness and designing your own positive emotions. So, next time you take a walk in the city, take a few minutes to look up at the trees, the birds, or the flowers on the windows.
You don’t need to wait for your next vacation to connect with nature. Here are some tiny experiments you can try this week:
Each of these tiny experiments takes minutes, costs nothing, and can be done in even the most urban environments. You can create a simple “I will [action] for [duration]” pact with one of those three simple actions and a short duration of five days up to a couple of weeks.
What tiny experiment will you try this week to find nature in your everyday surroundings?
