Seriously, guys. It doesn't work that way. Confidence is a state of mind that precedes any endeavor. If you're an insecure person and your game improves, you will still be an insecure person. You'll just have days where you feel cocky but then it will all fall apart when you play poorly. True confidence is consistency in attitude. It doesn't suddenly arrive one day when you become a good player. It's there helping you along as you go through the ups and downs of what it takes to get better. It's a belief in yourself that comes from within.
True confidence emerges from true consistency.
If you're at the stage where you likely to plant any given shot straight into the rail, confidence ain't gonna help.
