I really want to play basketball but I'm not that good.I practice at home but when it comes to practice I freeze up and I don't do well.I don't know much about Basketball but I go to practice to learn more. Coach always says negative things about my techniques so that I can improve them but I'm all focused on what I did wrong and I end up never getting better on my fault. When I play at my house I do really good but at practice I feel that I'm messing up considering that everyone else there has already been on a basketball team and I haven't. Is there any way I can increase my techniques even for a beginner in basketball?
