Creativity isn’t a personality trait you’re born with or without. It’s a thing you do, and get better at.

Treating creativity as a type of person is convenient for everybody: the ones who think they have it, and the ones who have decided they do not. In practice it behaves like any other practised ability, improving with reps, feedback and attention, and going rusty when unused. The people who seem naturally creative are usually the ones who have been quietly doing it for years.

Drop the sentence about not being a creative person and replace it with a schedule. Make something small three times this week, however bad. Compare what you make in December with what you make today and let the evidence settle it.
