Dribble Twice, Spin Once
So this trick will take a little bit of time to develop, but it’s probably the single most important thing that I’d recommend. When you watch a basketball player go to the free-throw line with the game on the line, he or she does the same routine every single time. It’s always some sort of dribble twice, spin once routine. With the spotlight on him, he doesn’t want to think about some small aspect of his form. He wants to not think at all. So he focuses on his trivial routine: dribble twice, spin once, shoot. The best he is hoping for is to shoot as well as he normally does in practice.
