For me at least I know the Martial Arts has literally saved my life. Otherwise I probably wouldn't be here today talking.
Martial Arts has helped me through alot of tough situations, both physical, mental and spiritually.
Also: regarding the tenets of TKD. I guess there good as far as teaching people to live a certain way, however not used in the original concept, they serve a good purpose. If only our TKD organizations would teach TKD properly and the way it should be taught, then I guess it makes for a good substitute.
Either way Martial Arts always comes from the heart first!!!!
