Art gives private emotion a public form.

Feeling stays trapped inside you unless it is given some outward shape. A song, a painting, a poem takes something entirely private and makes it something another person can walk into. That translation is the whole trick, and it is why art has never been a luxury for the people making it.

You do not have to be good at anything to use this. Write it down, play it badly, make the thing. Giving a feeling a form outside your head changes your relationship to it even if no one else ever sees it.
