Ronnie O'Sullivan

I don't think I suffered with depression, I don't think I'm a depressed type of person - I just think I suffered a depression to do with snooker, and I just couldn't handle it. I could go out and play, but take me out of there and I couldn't do life. It was a nightmare, my life just felt like a bit of a nightmare.

When I have a creative insight, there is a high. I think back in the day, I made music as much as I did because it made me feel so good. I think you could argue that there is a creative addiction - but, you know, the healthy kind.

Set your sights high, the higher the better. Expect the most wonderful things to happen, not in the future but right now. Realize that nothing is too good. Allow absolutely nothing to hamper you or hold you up in any way.

I keep saying I am an auto-didact, but I have a lot of outside influences. One I could cite is juggler Francis Brunn, who was the first man to throw ten rings in the air; he was really an amazing juggler who showed onstage the quest for perfection.
