Most people treat sleep like a phone charger — plug in when the battery's dead, unplug when you have to leave, and settle for 60% if that's all you have time for. But sleep isn't passive recovery.

They show up in your decisions, your relationships, your cravings, your stress response, and ultimately, in how you see yourself.
