Self-expression is a hallmark of an artist, of art, to get something off one's chest, to sing one's song. So that element is present in all art. It is the key to even standing up and saying, "Hey, listen to me." Self-expression can be based on looking at the world and making observations about it.

I'd say pot has been a break-even proposition for me.

The Human Species could have been great but instead we became satisfied with lights on our tennis shoes.

There are some people that aren't into all the words. There are some people who would have you not use certain words. Yeah, there are 400,000 words in the English language, and there are seven of them that you can't say on television. What a ratio that is. 399,993 to seven. They must really be bad. They'd have to be outrageous, to be separated from a group that large. All of you over here, you seven. Bad words. That's what they told us they were, remember? 'That's a bad word.' You know bad words. Bad thoughts. Bad intentions.

I think there's a little more attention to human needs than to property rights. But I don't think much of political activism. It's so shortsighted. Most people are interested in their own personal comfort. I've said that about environmentalists. I think they care about bike paths and places to park their Volvos, not the planet as an abstraction.

People who see life as anything more than pure entertainment are missing the point.

Singing is basically a form of pleasant, controlled screaming.
