You see after you practice and continue to learn how to hit shots and see the fun and value in learning to hit all these different shots on the practice tee then you will know, your subconscious will know, that you can hit that shot you are looking at. If the best of your ability does not produce the exact shot just then, it is no big deal because you have done your very best. Your pro will be proud of you, your parents will be proud of you and most important you can choose to be proud of yourself for doing your very best. After working so hard on this on the practice tee, take it to the golf course in a practice round. The important thing to really remember though here is we are talking about a game.
Games are to be fun.
Some are more challenging than others, but they are still games and are still fun. Whatever happens in any golf shot you hit, it will never change the person you are. You will still have friends who love you, your parents will still cherish you and all those important interpersonal relationships will still be there whether you hit this golf shot well or not. Go back to having fun. Try these drills.
