I got good advice once. Someone said to me: 'Live in your money rather than look at it.

Anyone who goes on 'The X Factor' to make big money will be in for a big shock.

On one level, going bust didn't bother me. It was the 80s, and there wasn't the stigma about bankruptcy that you might think. My mates weren't bothered. My dad was in business.. he knew that it happened, too. He loaned me the money to bail me out, and I got a loan from the bank to pay him back.

Anything I shouldn't laugh at makes me laugh. I mean, I'm bad at that, when somebody is singing something terribly and I'm thinking to myself, 'If I laugh now, this is the absolute worst thing I could ever do,' and then I start laughing and I can't stop.

The secret of my success is that I make other people money. And, never, ever, be ashamed about trying to earn as much as possible for yourself, if the person you're working with is also making money. That's life!

Maybe I am a bit mad.

When someone asks, 'Does success make you into a monster?' I always say, 'No, it enables you to be a monster.'
