You said there are a lack of JKD and BJJ schools near you, too bad. But keep doing the TKD and also join the wrestling team. Being a professional anything is a long term goal for a 15 year old, try to get some short term goals going in TKD and wrestling also. A lot of guys were tall skinny teenagers, that changes as you get older; take a look at your dad.
Try not to get into fights anymore and use sports or training as your outlet for your aggression. |
