I don't really remember, but from about the age of five I told anyone who would listen that I was going to be the best golfer in the world.

I started to really believe in myself, and my abilities, when I won the World Under-10 championship in Doral, Florida. I was nine and saw for the first time that I was amongst the best players in the world for my age. This was a massive confidence-builder for me.

I am a proud product of Irish golf and the Golfing Union of Ireland and am hugely honoured to have come from very rich Irish sporting roots I am also a proud Ulsterman who grew up in Northern Ireland. That is my background and always will be.

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.

My dad's a scratch golfer and I've got the knack of seeing something and then replicating it. I saw my dad swing a club and I worked out how to do the same thing. My backswing and follow-through have been basically the same since I was two.

With success comes expectation, and I know the expectation on me is going to be pretty high.

Sport was an obvious favourite of mine, and not only golf. I was, and still am, a big rugby fan.
