Maybe you make confusion between the coach and the driver of the car while following the athletes on the road. I don't know anything about golf, but doubt Tiger Woods could have won all his major without somebody teaching him thw right technique from the beginning.
A good coach is like a teacher, and without teacher there are not good students, also if are very clever.
Finally, I don't think you are who you are, and where you are, without the teachment of somebody in your life, starting from your parents when you were a child. Alone in the forest, you had only the chance to become like Tarzan, speaking the Language of monkeys, that sometimes are more intelligent than human beings.
