Sno .....no mulligans , play honest , or don't play . Scores when you are learning are irrelevant , focus on grip , smoothness , no tension in ur arms , making sure you play the ball as it lies , and of course putting .. Putt ,putt putt until you are sick of it , practice appraoch shots , the idea is to be deadly with the SHORT game , you putt twice or more times as you use the big silly stick.
Life ain't a dress rehearsal: Spread enthusiasm , avoid negative nuts.
