The Feedback Loop

Without feedback, practice is just repetition. You need a way to know immediately whether your attempt was correct. This can come from a coach, a recording of yourself, measurable results, or a self-assessment rubric.

A writer who publishes and reads the comments improves faster than one who writes into a drawer. A coder who runs tests after every function learns faster than one who writes an entire program before checking anything. The lesson is simple: shorten the gap between doing and knowing.
