People often call preparation luck after they miss the preparation.

Preparation is invisible from outside. Nobody sees the years of practice, the rehearsed answer, the reading done at night, so the moment of visible success looks like fortune arriving from nowhere. Calling it luck is often just a way of skipping the part that was boring to watch and hard to do.

When you catch yourself calling someone lucky, get curious about what came before. And when someone says it about you, name one thing you actually did. Not to defend yourself, but so you remember which of your habits are worth keeping.
