Having IT in golf or in any activity and in life in general is about going above and beyond what anyone else would do in every aspect of what your trying to do. Total dedication and concentration. I am a firm believer in that you get back what you put into anything you wish to do. Your have to believe in yourself and your practice contructively with convictions.
The truth is that when most people do anything they don't really give it their all in anything... and thats as true for touring professionals as it is for amateurs. The times in your life when your find that you are capable of anything is when you feel extraordinary pain and are off your cruise control coasting along happy and contented. Do you think it was a coincidence that when both Woods and Dimarco lost someone close to them suddenly they were the two at the top of the leader board that year because I sure don't....
When you do anything that intensely, it eventually becomes hard to keep it going but success is yours and the more time you put in on that level it will have an accumulative effect on anything you put your time into.
