Totally agree!

A book you keep coming back to is worth a hundred others. When I ask for recommendations, I always go for books people have re-read multiple times—it’s usually a sign they’re really good.

For me, I keep revisiting these gems: “The Wisdom of Life” by Arthur Schopenhauer, “The Fountainhead” by Ayn Rand, the “Foundation” series by Isaac Asimov, “The Stranger” by Albert Camus, “Escape from Freedom” by Erich Fromm, and “Mindfulness” by J. Mark G. Williams and Danny Penman.

I first heard about this from a podcast with Dr. Andy Galpin. He mentioned that when you sleep in a closed bedroom, CO2 levels rise through the night. As CO2 builds up, your body starts breathing faster to get rid of it, which can mess with your sleep and cause more wake-ups.

It makes sense if you think about it—humans evolved sleeping outdoors with fresh air, so CO2 buildup wasn’t an issue. But now, we mostly sleep indoors with windows shut, and that’s where the problem comes in.

So next time you sleep, try cracking a window open if you’re not doing that already 🪟

I did some digging and found out that immigrants have founded 55% of America’s billion-dollar companies. That’s wild! 🤯

I've noticed a trend on Twitter where people misunderstand what inflation really is.

When inflation goes down, it doesn’t mean prices drop—it just means prices are rising more slowly than before.

Central banks try to balance how much money is circulating with the amount of goods and services being produced, aiming for low and stable inflation as a policy choice.

Why? Because steady inflation is actually good for the economy. It encourages investment (since holding onto cash means losing value over time) and helps prevent deflation (when prices drop).

Deflation can be harmful because it makes people hold off on spending, thinking they’ll get a better deal later, leading to reduced demand, lower production, and potentially a downward economic spiral 📉
