Physical.
Assess your physical capability then crank it up a notch or 2. Do something that is cardio at your level . Walk, jog, run..every day - Diet, eat less/more of "good stuff", fiber fruit vegies. and lots of water. Balance, work on this 24/7.
Practice your short game. putt, putt, putt as soon as you can as much as U can chip, chip, chip... etc.
Drewitgolf - Communicate with him IMMEDIATELY. Please remember he is a professional and earns a living at his profession- Nuff said.
Oh yes, if I was your opponent I would be glad U know where all the water, bunkers and trouble is on the course. Try not to worry about it all the time. I would be happy to refresh your memory on every tee so you can try to miss the problems. OK

Thanks Bear. While I intend to put in the work, I also intend to make an attitude adjustment. I don't know which one will present more of a challenge.
