Nothing magnifies life — in the proper sense of the word, rooted in the Latin for “to make greater, to glorify” — more than the act of noticing its details, and nothing sanctifies it more: Kneeling to look at a lichen is a devotional act. We bless our own lives by recognizing and reverencing the details, the miniature marvels that make this improbable world what it is. https://t.co/glsftfClSk

New Trier rising senior Kennedy Glinn can't choose between field hockey and softball

Fortunately at Bates College next year, she may get to play both.

@oldbooksguy There are a lot of great ideas here but all I can think of is the poor zebra with the red dot.

[Stephen Marvin, FRM @stephendmarvin]

@AllDecisionEd I just checked out your website and love the work you are doing. I sent the link a long to my son's school.

[Stephen Marvin, FRM @stephendmarvin]

This is well worth the time. A comprehensive discussion of intergroup conflict. Fits well with Tim Urban's thinking ladder. @waitbutwhy

[Jay Van Bavel, PhD @jayvanbavel]

Want to learn more about the psychology of intergroup conflict and cooperation?

I discussed the effects of group identities, values, and beliefs, especially in politics, with @AnnieDuke

I feel like this sometimes.

Pandas can comfortably doze off in any location since they don't need to be selective, given their lack of natural predators to be concerned about.

The initial driver from my interest in decision making was being a better investor. How do others make decisions as well as improving my own? A related interest is how people interact with each other. The idea of "reality tunnels" is one of my favorites:

This is another one that I sent to my kids (early 20s). He's one my favorite young content producers. This has the added bonus including one of my other favorites (@kylascan).

[Jack Raines @Jack_Raines]

A long, but hopefully useful post with advice I'd give a 22-year-old preparing to enter the real world.

On careers, relationships, and navigating the next few years.

Wow! Not sure how I feel about this. This is a good follow if you enjoy the unexpected.

The Komodo dragon is the largest extant species of lizard & can eat up to 80% of its body weight in one meal

While it mostly eats carrion, the view of a goat that gets swallowed in one bite is truly impressive

@Peter_Atwater will join Steve on the show today to break down the Great Financial Crisis of 2007-8. Peter is an author, professor, researcher, and consultant. His work focuses on the study of confidence and how it affects the decisions we make.

[Stephen Marvin, FRM @stephendmarvin]

Before I started publicly posting, I would send posts that I thought were important to my kids. This is one of those.

I have been an active Twitter (X) reader and podcast listener longer than I have been a poster. This was one of my favorite early (for me) podcasts which had two of my favorite follows (@morganhousel,@jposhaughnessy, @infinitel88ps).

Good to remember.

[Adam Grant @AdamMGrant]

Comparison is not the thief of joy. Envy is.

Resenting others' success breeds misery and rivalry. Admiring their success brings motivation and learning.

We all compare ourselves to others. A key to growth and happiness is focusing our comparisons on people who inspire us.

[Stephen Marvin, FRM @stephendmarvin]

A bit morally ambiguous but makes a lot of sense.

How you take in information in critical. This article has some solid advice.

[Gurwinder @G_S_Bhogal]

Info is useful if it changes you. Most info on your feed is the opposite; you're exactly the same after consuming it as before.

Entire lives are wasted consuming useless info, but useful info is actually easy to find. I explain how in my new essay:

Definitely going to have to check this one out.

Psychologists have posited hundreds of cognitive biases over the years. A fascinating new paper argues that they all boil down to one of a handful of fundamental beliefs coupled with confirmation bias. https://t.co/bDDmNfsSie

Yes. Not as easy as it sounds.

The proper financial mindset is to be scared enough to save for the short run and brave enough to invest for the long run.

I love my outdoor walks, but that's interesting that walking inside or outside had the same general impact.

[Sahil Bloom @SahilBloom]

Steve Jobs had his best ideas while walking—this Stanford study explains why...

In 2014, a team of Stanford researchers examined how creativity levels were impacted by walking.

They conducted experiments with 176 participants that placed them in different situations:

• Walking on a treadmill facing a wall
• Walking outside
• Sitting inside facing a wall
• Sitting outside

In each situation, the participants were asked to complete a range of tasks that are typically used to measure creative thinking. For example, a test of "divergent thinking" asked the participants to come up with as many uses as possible for a set of objects.

The results were incredible:

Participants were dramatically more creative while walking than sitting.

In fact, one group of participants who took back-to-back tests, first sitting inside and then walking inside on a treadmill, saw a 60% improvement in creative output while walking vs. sitting!

Walking, indoors or outdoors, had a similar robust positive impact on creative thinking.

The authors concluded, "Many people anecdotally claim they do their best thinking when walking. We finally may be taking a step, or two, toward discovering why."

Many of history's greatest thinkers, entrepreneurs, artists, and athletes have believed in the power of walking.

It's a simple, free tool we can all use to dramatically improve our lives. Schedule more walks into your weeks.

Simple challenge for all of you:

Go for a 30-minute tech-free walk every single day this week.

• No phone
• No music
• No podcasts
• No articles
• No audiobooks

Just you, your thoughts, your gratitude, and the fresh air.

It’s a simple reset that will unlock new creativity and shift your perspective.

"Above all, do not lose your desire to walk. Every day I walk myself into a state of well-being and walk away from every illness. I have walked myself into my best thoughts, and I know of no thought so burdensome that one cannot walk away from it." - Søren Kierkegaard

Agreed. This reminds me that how you think is more important than what you think.
