A rock musician's career is short-lived. To extend it, you need to do other things to keep yourself fresh.
After a while, you just don't do things you don't wanna do - that's the great freedom you get, the older you get. You learn what to do and what not to do, and what will be a waste of time and what won't be a waste of time.
If I'm hanging around too much, my wife and kids say, 'Hey, why don't you go downstairs and start a new novel?'
I am not interested in anything that doesn't have a genuine heart to it. You've got to have soul in the hole. If that isn't there, I don't see the point.
