We're only human, we're supposed to make mistakes.

I tell the audience every night, "I hope you didn't pay more than face value on that ticket, because we ain't worth more than that, and you ain't gonna get any more than that."

I look in the mirror and think, 'I don't look like a rock star.' I talked about this with Bono and we looked at each other and decided we look like a pair of bricklayers.

If I ever reach heaven I expect to find three wonders there: first, to meet some I had not thought to see there; second, to miss some I had expected to see there; and third, the greatest wonder of all, to find myself there.

Everybody is different. Some writers can write reams of great books and then J. D. Salinger wrote just a few. Beethoven wrote nine symphonies. They were all phenomenal. Mozart wrote some 40 symphonies, and they were all phenomenal. That doesn't mean Beethoven was a lesser writer, it's just some guys are capable of more productivity, some guys take more time.

More than art, more than literature, music is universally accessible.

It's OK if you mess up. You should give yourself a break.
