Martial Arts

Try it out for a week, most schools will let you do that. If you like what you see, you like the other students, and you like the instructor, then try it for 3 months and reevaluate then. I recommend trying many different martial arts. Just don't let them give you a hard sell and sign you into a 1 year contract! Whatever you do, don't choose just one martial art and do only it for the rest of your life!
