Contribution gives talent somewhere worth going.

Talent without a destination becomes restless. It gets spent on demonstration, on comparison, on whatever presents itself, and none of that satisfies for long. A contribution gives it somewhere to go, which converts restlessness into direction almost immediately.

If your ability feels aimless, the missing piece is probably not more skill but a place to point it. Find something worth improving and attach your talent to it for a while. Direction often solves what more practice cannot.
