Many Taekwondo practicioners will have different opinions as to which is most important. Here are some opinions:
Experts might disagree on what is "most important," but the reality is that Taekwondo is effective as a whole and complete art, with nothing deleted, left out, or taught with a flawed approach. Thus, "integrity" (meaning "whole" and without "flaw") would be the most important for the individual, as well as the art itself. Lacking anything, such as courtesy with good manners and respect, perseverance, self control with high morals and ethics, or indomitable spirit would be less than what Taekwondo should be, and less than what a Martial Artists should be. It could be described as "balance" in training, "balance" in one's life, and "balance" in body, mind and spirit where all things are complete, and as they should be according to the "do" of Taekwondo.
