Everything in tennis is so neat and nice but boxing has sport down to its essence; it is very pure and I like that.

Learn to worship God as the God who does wonders, who wishes to prove in you that He can do something supernatural and divine.

I'd like to say that I am romantic person, but I don't think I am. When I won my first tournament I went into the crowd and kissed my girlfriend. I was 18 and didn't have my coach with me, I was there on my own, and I just needed to celebrate with someone I knew. I always start out with good intentions. I'll say something nice, then I'll just put my foot in it and ruin the moment.

The coming revival must begin with a great revival of prayer. It is in the closet, with the door shut, that the sound of abundance of rain will first be heard. An increase of secret prayer with ministers will be the sure harbinger of blessing.

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.

When I started to do quite well on the tour I thought I'd treat myself to a bright red Ferrari. I had always had a soft spot for them as a car brand and, when I was in the position to afford one, I decided to go for it.
