I wish to clarify that I have absolutely not made a decision regarding my participation in the next Olympics. On a personal level, playing in the Olympics would be a huge honour. However, the Games in Rio are still four years away and I certainly won't be making any decisions with regards to participating any time soon.

I want to try to become the best golfer in the world.

If somebody asks me whether I'd rather sink the winning putt in the Ryder Cup or win a major, it's the major every day. World championship or Ryder Cup? Win a world championship. At the end of the day you're going to be remembered for what you achieve in an individual sport.

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.

As long as I keep enjoying my golf, then hopefully I'll be able to play well.

Since turning professional at 18, I have travelled the world playing the game that I love and consider myself a global player. As the World No.1 right now, I wish to be a positive role model and a sportsperson that people respect, and enjoy watching.

My mom and dad worked very hard to give me the best chance in - not just in golf but in life. You know, I was an only child, you know, my dad worked three jobs at one stage. My mom worked night shifts in a factory.

It's incredible, ridiculous really, isn't it? You realise you can make more money on the golf tour in one week than some people make in a lifetime.

Going to the gym is great for your body, but it's also great for your mind.

To be a top-class athlete, you have to train hard, you have to eat right, you have to get enough rest. I feel the way golf is going nowadays, you have to treat yourself as an athlete.

The next time I cry about golf it will only be with joy. It's not worth crying over golf for any other reason. After all, it's only a game.

I mean I don't want to feel inferior to any other golfer in the world. You know if you do that, then you know you're giving them an advantage, you know, right off the - you know, right from the start.

This is the great thing about Northern Ireland. I walk down the street and people stop me and say things like, 'I know you. You're that wee golfer, aren't you?' I say, 'Yeah, that's me.' They say, 'Keep it up, wee man.' It's very funny and that's why I want to stay here as long as possible.

Two years ago, of course, I was just a rookie and listened to everybody. In a way I am still a rookie. I'm only 23 and I'll be surrounded by great players who have played in a lot more Ryder Cups than myself. But the rankings say I am the best player at the moment and so that brings a responsibility.

I receive huge support from Irish and British sports fans alike and it is greatly appreciated. Likewise I feel I have a great affinity with the American sports fans. I play most of my golf in the U.S. nowadays and I am incredibly proud to have won the U.S. Open and U.S. PGA Championship in the last two years.

There's a certain - there's a different pressure with playing in a Ryder Cup. You know, you're not just playing for yourself. You're playing for your teammates. You're playing for your country.

I really enjoy playing 'Tiger Woods' on the Wii, and you can set the levels to easy, medium, or hard, so I think it's definitely a good way for kids to learn the motion of a golf swing if they want to get into the sport. It makes it more fun for them as well.

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.
