I don't actually go to that many concerts.

Since there are a wide range of entrepreneurs fundraising at any given time, I looked at each opportunity as it has arisen and on its own merits. Then I've sat down with my financial advisers, we've looked at the numbers and gone for the businesses I believe have real potential.

I tend not to argue about things that I don't believe in.

I think most players would love, at one stage in their career, to say, 'I've been No. 1 in the world.

I've realised over the years I play my best when I have time to prepare for each tournament as best as possible.

Let it be your business every day, in the secrecy of the inner chamber, to meet the holy God. You will be repaid for the trouble it may cost you. The reward will be sure and rich.

Tipping generally changes depending on where you are in the world. In Britain you don't always have to tip, but I always make sure I do. I have a lot of respect for waiters and waitresses - it can't be an easy job and they often don't get paid huge amounts, so I think it's important to reward them and let them know if they are giving great service.
