I didn’t buy one-hundred percent of everything he wrote, but I’ve been impressed by a few points. One of them is the 12th.
Minimize your own cognitive load from distracting things that don’t really matter. It’s hard to overstate how important this is, and how bad most people are at it.

When reading I immediately recalled the Zeigarnik leak effect.
