Great performers including golfers focus upon and remember their good shots, not their bad ones. Choose to remember your winning shot and not the missed putts, errant shots, topped drives, etc. Listen to any Tiger Woods press conference and the man refers to the good he accomplished during his round. Likewise, Jack Nicklaus never admits to ever 3-putting an 18th green or shanking a shot, though the facts contradict him. In his mind, he is strong and pure!
