Due to work, I have a limited time available (2 nights per week. Maybe 3 on occasion). I would like to get "rooted and grounded" in one system, with the option to branch out in the future if I choose. There are a million taekwondo dojangs in my area, compared to only 1 quality Hapkido dojang, where taekwondo is also taught. I am told the instructor is much harder and demanding on Hapkido students than Taekwondo students, and it takes far longer to achieve 1st Dan with Hapkido. My solution? Pick the best taekwondo school in my area. Immerse myself in taekwondo with the goal of achieving black belt within 4 years. Then, if I choose, I can take hapkido because the kicks, punches, and strikes will be related. Everybody says that Hapkido is better than Taekwondo for self-defense; however, I have a belt in nothing right now. I'm thinking that a green belt in taekwondo from a great instructor will dramatically improve my self defense ability. What do you experts think?
