I can't do anything in moderation.

I grew up having to piss in a bucket ’cos there was no indoor shitter, and now I have these computerised Japanese super-loo things that have heated seats and wash and blow-dry your arse at the touch of a button. Give it a couple of years and I’ll have a bog with a robot arm that pulls out my turds, so I don’t have to strain.

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.

There are no unachievable goals.

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.

I wanted to be the fifth Beatle.

Ten thousand million nightmares, temptation by the score, I used to get so high, and still I wanted more. You think my time is wasted in search of who I am, I tried so hard to kill the boy inside the man.
