Selflessness implies fun. Its fun to be free. Freedom is inner stillness and not being haunted by your desires, your fears, your aggressive tendencies. . . it's being cool.
When I was a kid, I felt like I could do anything and play anything. I just felt super-confident. And then, once I started to play music professionally, maybe it's from being from a small town, but you grow up and then you're suddenly a big fish in a small pond, and I realized that there were a billion other drummers out there that could play as good as you or better, and everybody wants that job.
