With all due respect to your dad, I never bought into that line of thinking. If you know what the right shot is and you know that you have the potential to make it happen and yet the desired outcome still eludes you, I think you have every right to be mad. How else are you going to get better? In my opinion, that type of thinking draws an imaginary line in front of you which says that you're not "there" yet and that you don't have "permission" to get mad and that begs the question: "At what point do you officially 'get there' and at what point are you officially allowed to get mad?" It's sort of like walking onto a dance floor and then making the conscious decision to begin dancing. A similar and quite common line of thinking is the idea of being "allowed" to play from certain tee boxes; how will you ever know if you can handle the next set of tees if you don't try? And if you DO try and you become overwhelmed, does that mean that you can't handle them, or does it simply mean that you have to learn more? To this day (as I always have) I still get mad at myself when I mess up something that I know in my heart I am more than capable of doing and that's what keeps me moving forward. I believe that if I settled for "where I am" and then waited for "permission" to take the next step, I'd still be waiting to break 100. Getting mad is good. It clears the air and helps you focus and forces you to do better. At least that's the way I see it. -JP
