The day you stop being teachable is the day your competition starts catching up.

Skill has no resting state. The moment you decide you have learned enough, you stop adding while everyone slightly behind you keeps adding, and the distance closes without you doing anything wrong in particular. Being uncoachable rarely feels like arrogance from the inside. It feels like already knowing.

Notice where you go defensive when someone corrects you, because that is usually where you have most stopped learning. Ask one person whose opinion you actually respect what they would change about how you do it, and let them finish.
