Practice isn't the thing you do once you're good. It's the thing you do that makes you good.

The line rejects the common belief that practice is merely a way to maintain skill after talent has already been proven. Instead, it frames practice as the causal engine of competence: repeated, effortful rehearsal is what produces “goodness” in the first place. In Gladwell’s broader popularization of expertise research, the emphasis falls on process over innate gift—skill as something built through sustained work, feedback, and time. The quote functions as a corrective to status-based thinking (“the good practice”) by making practice the prerequisite rather than the reward, encouraging a growth mindset and demystifying high performance.
