Learning and delivering are two different things VERY DIFFERENT
Learning or acquiring and delivering are widely two different acts. Most golfers are attempting to learn all the time ,hence carry on with the same mentality even when playing a game to the best of ability.. When it comes to playing a game it is delivering what you know .both knowledge and skills. Any attempt to learn when playing a game is suicidal.
Nutty professor learn all life without delivering any to any.
To much in the head is like a over filled bus where every one rushing to the door to get out and not one gets to get out
