Junk in the pantry

2025-09-30 19:09:00

The more junk I have in the pantry, the more junk I end up eating.

Often, improving the odds of making better choices isn’t about more willpower – it’s about removing bad options in the first place.

Environment shapes behavior.

Design your environment so the better choice becomes the easier choice.

Electric shock vs. reflection

2025-09-29 19:57:00

There was a recent fascinating experiment with a group of undergraduate students who are part of the digital/social media generation.

In the first half of the study, they experienced a collection of stimuli (a spanish guitar riff, an exposure to a cockroach, an electric shock, the sound of knife scraping) and were asked to share how much they’d pay to avoid the bad stimuli. Most folks said they’d pay $1.5 to $2 to avoid an electric shock.

They were then asked to entertain themselves with their thoughts for 15 minutes in an empty room. They were told that they could choose to experience one “randomly selected” stimulus during this period.

In reality, all participants were given the “electric shock” option. A computer recorded whether and how many times the participant chose to administer an electric shock.

25% of the women and ~70% of the men found it preferable to shock themselves rather than sit with their own thoughts (study summary).

Mindblowing.

Virality and extreme views

2025-09-28 19:20:00

When I reflect on the biggest global changes we’ve seen in the past 20 years, I think of politics powered by social media and virality.

This graph beautifully shows the representation of extreme views in all traditional media vs. cable TV vs. social media.

As extreme views increasingly become commonplace, so does its place in politics.

New parent talk

2025-09-27 19:03:00

When I talk to new parents, I give just one piece of advice: Keep extremely low expectations – and let life exceed them.

I don’t share tactical advice because every parent figures out the tactics over time. That’s not the hard part. The real challenge is managing your mindset – living through the inevitable ups and downs, and sitting with the discomfort of losing the control you once had.

It’s tempting to over-optimize: the nap schedule, the sleep routine, every regression or phase. But the truth is, babies are doing a tremendous amount just by growing and making sense of the world.

Routines will come with time. Consistency definitely helps and can be a high probability strategy for many kids. But outcomes won’t always match the plan.

And that’s okay.

No eight-year-old struggles forever with sleep or with getting to the bathroom to take a poop. These things work out in time.

The reason I love lowering expectations is because it reminds us to let go a little, stay consistent where it helps, and – most of all – calm down.

Crystal Hut

2025-09-26 19:14:00

There’s an eatery on the slopes of Blackcomb Mountain at Whistler-Blackcomb in Canada called Crystal Hut. It’s on the far side of the mountain and takes effort to get to.

But once you get off the chair, you are drawn in by the smell of waffles and maple syrup.

When I got there, I was reminded of Scooby Doo following the smell of food. The smell was that memorable.

You then get to a small log cabin – that gets very crowded during lunch time – where friendly staff serve the tastiest waffles with exquisite maple syrup, berries and such. It’s been over more than a year since we went to Crystal Hut and I still think of the place every time I see a waffle.

I’ve eaten waffles many times over the years. They were all events that I had, for the most part, forgotten.

Not at Crystal Hut though.

It wasn’t an event, it was an experience.

It made me realize how the most memorable experiences have a way of engaging many of our senses. In this case, the combination of the view, the taste, and the smell combined to transform something seemingly ordinary to an unforgettable memory.

How we wait

Sometimes the sternest test of our character isn’t in how we hustle when the chips are down.

It’s in how we behave when we have to wait.
