Its about being in the moment, not of the moment, not about the moment. Closest thing to me comes from my attempts at being a musician, if you want to play the way you hear your hero's play, you can not listen to your self as you are playing, you can only surrender and play. After there is all the time in the world to try to relive that moment, but its lost. Practice your fundamentals,,,, alot then play each time for the pure pleasure of being in that moment.
The only way to become that world class performer is to put yourself in the mix and become the moment.
