The one strongest, most important part of my game is that I want to be the best. I won't accept anything less that that. My ability to concentrate and work toward hat goal has been my greatest asset.
I don't think you ever will yourself to win. I think you prepare yourself the best you can, get yourself in the best mindset you can get in, and go after it.
To sink a six-foot putt with thirty million people looking over your shoulder, convince yourself that, if you miss it, you will be embarrassed and poor.
