Making art

My definition of art contains three elements:

1. Art is made by a human being.
2. Art is created to have an impact, to change someone else.
3. Art is a gift. You can sell the souvenir, the canvas, the recording... but the idea itself is free, and the generosity is a critical part of making art.

By my definition, most art has nothing to do with oil paint or marble. Art is what we're doing when we do our best work.
