why are you boxing, if you have a fear of throwing punches. the only reason i think you would possibly fear is really hurting the person. have you had alot of street fights growing up? do you think that if you let loose, your anger will come out as well. i myself sometimes hold back from punching bcs i actually dont want the guys i spar with see that i am actually trying to knock their heads off. its not personal, but thats how i feel. its a control "flaw" i have. i am in control, persay, but i still have to win. nomatter whether its a sparring session, or a match. i have to do the best i can for me. i have had alot od street fights growing up and i have hurt alot of people by my jab. i am older and wiser now and a little more understanding of the psychology of fighting. it brings out the animal in most of us. plus i have 2 children now as well. i understand violence and fighting a whole lot better now bcs i would fight, and or kill, with my own hands, anyone who would try and hurt my family and most of all my children. so, needless to say, i hold back sometimes from clocking my sparring partners.
