I play piano. I used to do artwork (painting, drawing, etc). I'm more focused on music right now, but every once in a while I find a way to be artistic--I doodle in class, I play with photoshop, do web design, etc.
Creativity is a big part of my life. I'm not saying I'm a creative person, but I enjoy activities that require at least a little creativity.
I find them to be activities that inherently worth my time. That is, I don't play piano or draw for the end result, but for the experience itself. It's self-rewarding. Sure, it's nice to show off your stuff in front of an audience once in a while, but it's not why I do it.
You can describe it as a positive escape from reality. People often use TV or video games to escape stressful and difficult lifestyles. But once they return from the TV, the problems still exist; i.e. it's a negative or neutral escape from reality. Creativity, on the other hand, is a positive escape. You leave the activity feeling replenished. And you accomplished something while you let your mind focus away from day-to-day difficulties.
And it looks like there might be a nice reward for this type of lifestyle!
