You know, “Sleep is not the absence of wakefulness” completely flips the script on how we view rest. It’s not about what you’re missing when you’re asleep, but what you’re building for when you’re awake. This one idea, honestly, changes everything if you really let it sink in.

Meaning
Sleep isn’t a passive state of ‘off.’ It’s an active, biological necessity that constructs your ability to be alert, focused, and emotionally stable when you’re awake.
Explanation
Look, we’ve all been trained to think of sleep as downtime. A blank space in the calendar. But that’s where we get it so wrong. Walker’s point is that your brain and body aren’t just idling. They are in a state of intense activity—repairing tissue, consolidating memories, clearing out metabolic waste. It’s a building phase. Think of it like this: wakefulness is the performance, and sleep is the intense, behind-the-scenes rehearsal and renovation that makes the performance possible. You can’t have a great show without the prep work. And cutting sleep isn’t gaining time; it’s literally dismantling the foundation of your next day.
