I've been lucky to find a trainer who can teach me all the skills and nuances of boxing without all the brain trauma. That alone is what keeps me away from truly "going for it" in boxing. I also don't think I have the dedication needed. I can work hard, and I go to the gym 5-6 days a week, but I am not competitive and I don't have the desire to dedicate my whole life to just boxing, there are more things that life has to offer, and even in martial arts, if you just box you are limiting your knowledge.
