Re-Up The Five Pillars Every 24 Hours
The foundation is five things: sleep, nutrients, movement, light, and relationships. Huberman's shift was to stop thinking of them as a list and start thinking of them as a daily re-up. He says you can coast for a day or two, then you hit a wall where nothing else functions.
The play
Make a five-item daily check: sleep, nutrients, movement, sunlight, one relationship touchpoint. Each day, put something into all five. If you skip one for two days straight, treat that as the real problem before adding anything new.
