some people prefer doing the forms, whereas others prefer sparring and going to competitions. sometimes people say that there are martial artists who pay full attention to forms only because they are not good at sparring. would u agree? is it possible to advance to the black belt without sparring? does it make any sense since tkd is a martial art? does a black belt holder has to be a complete person in his/her skills, meaning does (s)he have to be able to do forms, break boards, fight, use self-defence successfully, be aware of the philosophy behing this martial art...?
