Ronnie O'Sullivan

“I've been semi-successful. I've done all right but I'm not the player I was. Who do I think will win the world championship? John Higgins. Have I been good for snooker? I don't know.”

“My dad's method in his madness was to try every sport and then observe what I liked. I played football, tennis, golf, cricket but I loved my snooker.”

“The most important thing, the biggest love of my life, is my snooker. I've never been so emotionally ingrained in something - in a person, an object, anything - as I have in snooker.”

“People think I don't like interviews but I don't mind speaking about proper and interesting stuff. When it's stupid stuff to build your image and you are told to mention this and mention that, I hate it.”

“Running clears my mind, and gives me a reason to get out of bed in the morning.”

“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.”

“Looking for perfection is the only way to motivate yourself.”

“The relentless pursuit of perfection has been my problem over the years. It's maybe held me back.”
