if you had to take a guess or know from experience how long does it take to reach first dan black belt TKD.
i've only trained at an MMA gym and i would like to actually get belts and find a deeper meaning to fighting than just beating the hell out of someone.
I personally would like to caution you against taking a martial art just for belts. On the one hand, there are "McDojo's" that will just give out belts without really teaching you anything at all. Then at the other extreme, you have very traditional schools that will promote you at that head instructor's discretion. One way you will feel unsatisfied with you belt or get impatient wanting to just get a "black belt". I took Tae Kwon Do daily for two years, I gave up a lot of time to get that belt in just two years; my Grandmaster was demanding. Bottom line: don't take a martial art just for a belt, and behind all the pretentious tenets and ideals martial arts is a physical expression that can very well end up in having someone beaten to a pulp.
