But I don't think you will have much fun on the course or play your best. You have a choice to make about what you say to yourself. You have to believe in your ability and have a positive attitude to play your best. It's easy to forget someone else's criticism of you, but it's not easy to forget your own criticism of yourself. You must monitor what you say to yourself and not cut yourself down with negative self-talk.
Negative thoughts lead to low self-confidence and negative outcomes.
Most golfers don't pay attention to what they say to themselves and often berate themselves when they play poorly. If a professional hits a ball in the water he simply sees it as a fluke and expects that it won't happen again. You can be sure Lee Trevino doesn't tell himself what a bad player he is when he hits a poor shot or hits it poorly one day. No one can be positive for you but yourself. You have to make the choice to keep self-talk positive and helpful.
