It's like if you're an astronaut and you've been to the moon, what do you want to do with the rest of your life?

One may not eat what has a face.

I think the minute you're full up and have had enough to eat, then that's time to retire.

I would have liked the Beatles never to have broken up. I wanted to get us back on the road doing small places, then move up to our previous form and then go and play. Just make music, and whatever else there was would be secondary.

Domesticity is the enemy of art. I don't know if that's true. You can write good happy songs. So, I don't think it's necessarily happiness. But I think self-satisfaction is maybe the enemy. It's kind of better to think, "Tomorrow night I'm gonna sing it better." There is this forward effort. It feels to me right, it feels human.

No matter how accomplished or how many awards you get, you're always still thinking there's somebody out there who's better than you.

At the end of the Beatles, I really was done in for the first time in my life. Until then, I really was a kind of cocky sod.
