Your Brain's Hidden Limit (Most Never Notice)

In 2025, the silent enemy of productivity is decision fatigue. CEOs average 35,000 decisions daily, but by 2 PM, an executive function crash often occurs, causing the brain to make 47% worse choices. You're not lazy; you're experiencing willpower depletion.

The Invisible Depletion Clock

Every choice costs 3.1 grams of glucose. After making 50 decisions, your brain has burned the equivalent of a candy bar's worth of fuel. This leads to overchoice paralysis, where your prefrontal cortex literally goes offline after lunch.

Sign #1: "Everything Feels Hard"

  • Simple emails → 15-minute debates
  • Grocery shopping → Overchoice paralysis and anxiety
  • "I don't care" becomes the default answer to avoid more choices
