I think if a man can create something like an atom bomb, he can surely create something with his own mind.

With my recovery programme, I have to do a daily inventory of how my day has been. I am terribly dyslexic and have attention deficit disorder, so I have to carry a tape recorder everywhere I go.

Being sober on a bus is, like, totally different than being drunk on a bus.

I've been dictating to my son, who's helping me on his computer. I'm spending a lot of time doing research - I've just got up to 1971, when I went crazy and dived through the window. My life is so full of interesting stories.

I never thought I could write anything or do a show sober, ever. But I did the Black Sabbath shows sober, and it was so much better fun for me, and everybody.

When I was doing drugs and alcohol, I thought I'll have a drink and a line of this and I'll smoke this. I didn't go, 'Then I'm going to go out and get drunk, come back strangle my wife and wake up in jail on charges of attempted murder,' but that's what happened. I'm not telling people what to do. If they can enjoy doing it and they get on with it and they can handle it fine, but don't involve me. I'm lucky to be alive; you're playing with Russian roulette.

I can't do anything in moderation.
