hey, Tdk instructor here, if you really want to learn the basics of Tdk just know that first and foremost its supposed to be a "military" martial art, meaning that mastering a few techniques and body conditioning is more important than flashy moves or breaking boards (modern day tdk is not such thing), if you are not interested in the sport or becoming a "full" time practitioner just remember that in traditional martial arts conditioning an technique are more important than some other aspects, if you are interested in learning self defense and want to truly cover your bases, start with boxing and some grappling art (wrestling or judo, then bjj), do that for a few years or at the least 6 months, then change style
REMEMBER THE ONLY THING YOU NEED IS TO KEEP PRACTICING, NEVER STOP
i wish you luck in your training
