I did Shotokan Karate for 3 years in high school, had a brown belt. I realized how unrealistic it was and pursued other martial arts when I went to college. Did some judo, then I found Brazilian Jiu-Jitsu.
My school is heavily influenced by the Machado style of bjj. I've been doing it for a total of about 2 years and I still proudly wear the dirty white belt and a gi that has lots of blood stains on it.
