Fighting is all about attitude, IMO. You have got to fight like you have nothing to lose. In the beginning of a fight both people are throwing blows, more focused on hurting their opponent than defending themselves. Then, there is usually a turning point where one guy starts to lose the will to win and becomes solely focused on not getting hurt. That person usually loses and gets hurt. Don't be that person. No matter what keep fighting, keep punching, keep swinging, kicking, biting, scratching, go rough ridin' apeshit on this dude. As long as you don't give up, you know that he will give up first, and you will win.
