Golf's mistakes can seem pretty random: You hit it left one day, right the next. The shanks turn into the fats. But every golfer has a basic shot pattern, and that's what you need to identify. Look at your mis-hits over five rounds or several sessions on the range. Your pattern will reveal itself. Are your tee shots starting right or curving right? How about your irons--fat and thin or off-center contact? We bet you can pin your struggles on one or two types of faults. Then use the fixes here from 11 of Golf Digest's Teaching Professionals. You'll take the guesswork out of your game.
