The guys that have the hunger to win, and the consistent discipline all the way thru everything they do, in whatever part of the process they are doing, from research to execution, are the ones that win the most. Do each and every detail and technique/strategy you can actually control, properly, and the only variable left is the wind, weather and your mental state that day. And we are all our own worst enemy in dealing with the mental state, and that is what usually beats us, one doubt, one chance, one mistake.
