On the Old Course at St. Andrews: This is the origin of the game, golf in its purest form, and it's still played that way on a course seemingly untouched by time. Every time I play here, it reminds me that this is still a game.

All the things that I have derived either directly or indirectly through the game of golf are things I owe a great deal to the game and to the people who support the game.

I am so pleased with my golf course. I am to say that it's the best I've ever seen it - without equivocation.

I enjoyed the fans thoroughly, and they were always helpful. They were the reason that I tried so hard over the years.

Many people don't know that I experienced a blood clot caused by deep vein thrombosis, or DVT, which is when a blood clot forms in a deep vein in the body, often the leg or thigh. I'm fortunate that my DVT was diagnosed and treated before it led to something even more serious and that's why I encourage people to talk to their doctor if they think something is wrong. I've teamed up with Janssen Pharmaceuticals to raise awareness about blood clot prevention and treatment.

I've drawn a lot of inspiration from people who have supported me, golfers who have helped me. If it wasn't for the game of golf I'd probably be mowing the greens back in Latrobe.

I remember ones I lost [shot]. I remember the ones I won, but I remember the ones I lost, something that I will never forget. Did it ruin me or hurt my career? It taught me about life, how to take the bad with the good.
