i believe you need discipline the most. like ryanhall said. this might sound a little weird to you but if someone tries to start shit with you dont give them what they want. if you do you might end up getting hurt. but if it comes down to it and you think you are in danger use your training
. for instance to avoid a fight is to run, talk your way out of it, and never ever hesitate to fight cheap.
for you training -- jog, easier said than done, i personally dislike runing because its so damn cold where i live. last night it was -23 with windshield factor
.i can't wait till i am an adult so i can get out of this cold prison
