When I was a youngster, how I learnt more than anything else was by copying -- it is the greatest facility any young individual has. It's a facility that we do have all our life, but when we're younger we tend to use it more; when we get older we tend to get more analytical. We push that copying device to the back of our minds. But I think it is probably the single thing that we do that helps our progress most -- especially in golf. You see a good player and it rubs off. But that's not enough for a lot of people. They go off, get to seventeen to eighteen years of age and want to know for themselves why. They delve into the mind, and really sometimes certain things are best left alone.
