How can I get myself to be more assertive?
PLEASE HELP!!! I have a serious problem with being WAY too shy. Whenever I talk to someone I don't really know well or someone I just met, I feel really awkward. Also, I take karate. You know how sometimes you have to yell when you punch or whatever in karate? Well, my karate teacher always tells me that I don't yell loud enough, and that if I don't improve, I might just fail my black belt test because of that. But I just can't get myself to yell loud enough because I am too shy. So, have any of you guys ever been really, really shy, but you got over it somehow? If you have any tips, please tell me, because I really need help. Thanks a lot!
