Martial Art's What One?
My sugestion for picking an MA is to ask yourself why your picking it- what is your goal, etc.
If you want inner development try Tai Chi, Capoeria, or Akido.
If your wanting Flash, do forms pick a traditional Mc Dojo MA.
If you want to something competitive for fun pick an MA that has Sparring like Karate, Kick Boxing, TKD,etc.
If you want a Harder Contact Competitivenes, go Boxing, Judo, Wrestleing, Mauy Thai, or BJJ.
If you want to learn how to Street Fight, go take Military Mauy Thai, Krav Maga, or cross train in boxing, Judo,Mauy Thai, and BJJ. [A striking and grappleing art] and learn the differences.
If you want Eastern Spiritual Development, take a course in it at the local JC, or Buddist Temple. Even go to Borders and buy a book on whatever you seek. Don't try to seek it in a Dojo. You'll be dissappointed. Most of the Dojos that offer Spiritual developments are usually Quasi to Full Blown Cults who exsist to take your money by taking advantage of people who need something bigger than themselves to belive in. In other words be careful on whats out there.
