But then there's a little part of me that says, 'You know what? I still think I can get better, I still think I can do this and that.' That's what keeps me going.
Even though this is my 12th year on tour, I love what I do. There's always a challenge. There are things I want to improve on, things I want to change. That's what keeps me going.
It's obviously going to be very, very hard and nobody has ever done it, ... I know that. But for me, that's kept me motivated. That's what keeps me motivated in the mornings, to have a huge challenge ahead of me. I just want to test myself to see if I can really do it.
I play this game for myself, and I motivate myself and I have my own goals, and I think I know my limits. I know what I want to achieve. There are a lot of young players coming up, and they are very good. But I also love being in the spot that I'm in, so that keeps me motivated.
