I would personally recommend boxing, or fisticuffs if you're feeling fancy, since it requires just as much discipline as any Eastern martial art (I also did kenpo karate and Taekwondo for 2 years) and I've found works better for actual defence. Besides that, there's very little of the mysticality that is often found in Eastern martial arts. But remember, to each their own. Try out different ones. Find which one fits you.
