I follow three rules: Do the right thing, do the best you can, and always show people you care. You’ve got to make a sincere attempt to have the right goals to begin with, then go after them with appropriate effort, and remember that you can’t really achieve anything great without the help of others.
In golf, the player, coach and official are rolled into one, and they overlap completely. Golf really is the best microcosm of life - or at least the way life should be.
I'd say handling people is the most important thing you can do as a coach. I've found every time I've gotten into trouble with a player, it's because I wasn't talking to him enough.
