I started with basic judo when I was 8 years old, I'm now 37, and still going strong with my studies. You'll find there may be times that you have to put your classes on hold, or you get discouraged with the school you're training at. Take a little time if you need it. Always read anything that interests you about different styles. The more you study, the more diversified your abilities, the better martial artist you will be. I have studied judo,wing chun, akido, shaolin gung fu, jeet kune do, arnis, kali, wah lum gung fu, small circle jujitsu, ryuku kempo, kyusho jitsu, toaism, budhism, and I'm still searching to see what works best for me. Do not limit yourself to one way of thinking. Keep your tea cup empty when you come to drink at the table of knowledge, and you will go far with your studies.
