Lessons are not to take the place of practice, but to make practice worthwhile.
Make a game out of practice, you're still a child at heart
Never try a shot you haven't practised.
The woods are full of long drivers.
I learn teaching from teachers. I learn golf from golfers. I learn winning from coaches.
In golf your strengths and weaknesses will always be there. If you could improve your weaknesses, you would improve your game. The irony is that people prefer to practice their strengths.
