Rory McIlroy

I wanted to make a point of basing myself at home, being close to my family. I'll never be able to repay Mum and Dad for what they did, but at least they know they'll never have to work another day. I'll do whatever it takes to look after them.

On the course, I sometimes eat a little sandwich or a slow-release energy bar - one on the front nine and one on the back nine. You're out there five hours, so you have to keep eating. You're going to burn at least 1,000 calories. I'll try to take in about 400-600 calories during a round and drink water.

The Olympics will be great for the growth of golf on a global scale, but my focus right now is on being the best player I can be, trying to win Major Championships and contributing to what will hopefully be a victorious European side at the forthcoming Ryder Cup Matches against the USA.

Self-indulgence is something to watch, but anything that helps you understand situations that are difficult to understand is good. If you're having some sort of emotional trauma, you need to find a person to talk to about it who says, 'This is quite normal; it's fine.'
