If you feel like you’re working hard but not improving, you might be stuck in the performance zone. In his TED Talk, learning expert Eduardo Briceño explains how when you master a skill — whether it’s a hobby or a task at work — you tend to stay in the “performance zone,” where you focus on what you already can do and not making mistakes. Real growth, however, he says requires you to switch to something called the “learning zone” where you focus on the skills you haven’t mastered yet. “What if, instead of spending our lives doing, doing, doing, performing, performing, performing, we spent more time exploring, asking, listening, experimenting, reflecting, striving and becoming?” he asks.
