A couple of hours of practice is worth ten sloppy rounds.
If you win through bad sportsmanship that's no real victory.
My philosophy? Practice, practice, practice and win.
Don't worry. Just leave everything in the hands of God.
Practice, which some regard as a chore, should be approached as just about the most pleasant recreation ever devised.
The more you practice, the better. But in any case, practice more than you play.
