Which Martial Arts should i choose?

Mixed martial art is a good choice but i suggest wing chun or jeet kune do cuz wing chun and jeet kune do focus on real life fighting so they would train your speed,strength...and of course your fitness level must be good.Jujitsu will involved a lot of grapping and it wont work on someone who is fiter or stronger than u.Taekwando and karate won't be effective for real life fighting but it will increase your fitness level if u train hard.Muay thai is also good.I truly suggest wing chun or jeet kune do.
