Focus

Attention behaves less like a switch than like a budget: finite each day, spent by everything you engage with, and refilled only under specific conditions. Most people try to solve focus problems with more effort, when the effective levers are usually upstream — what you let into the day, and what state your brain is in when you ask it to concentrate.

This pillar covers how attention actually works, why fog lifts more slowly than people expect, and how the brain rebuilds capability through repetition rather than intensity.
