Re: How to improve your basketball confidence
To improve basketball confidence:
Play against decent opposition that you are not familiar with.
Play with much better players than yourself -bit of a double edge sword here, as they can be so good it discourages you or it can make you better so when you play against your usual competition.
Practice, I mean do actual drills. Not playing pickup ball, over the years I found that pickup ball whilst fun doesn't do anything for my skill level. To actively improve, you have to practice.
