Deliberate Practice vs. Mindless Repetition

Doing something a thousand times doesn't make you good at it — doing it a thousand times while paying attention to what's not working does. Repetition without feedback is just motion. You can play guitar for ten years and still sound like a beginner if you never slow down to fix your weak spots.

Deliberate practice means isolating the hard part, working on it at the edge of your ability, and getting feedback — from a teacher, a recording, a test, or just your own honest assessment. It's uncomfortable by design. If practice feels easy, you're rehearsing what you already know. Growth lives right at the boundary of I can almost do this but not quite.
