Creativity is a habit, not a gift you're born with
The romantic myth of the natural-born genius does a lot of damage. Creativity is mostly practice and attention.
We tend to file creativity under things other people are born with. The evidence, and most working artists, say otherwise: it's a habit you build, not a lottery you win.
Mostly it's editing
Creating rarely means conjuring something from nothing; far more often it's choosing, arranging and cutting. The cook, the painter and the playlist-maker are all doing the same thing, making a series of small, confident choices.
Xciting Art makes this case nicely in "you're more of an artist than you think", everyday creativity runs on the same engine as the gallery kind.
Feed it daily
Pay deliberate attention to one ordinary thing a day, copy what you admire to learn how it works, and finish small things often. Momentum, not inspiration, is what compounds.
