Congratulations! I'm basically a brown belt (my school has weird belts lol) and can tell you that you'll be a high rank before you know it. Try to stay in martial arts, the physical workouts as well as the kind and supportive community aspect of it is incredible. I can honestly say from my experience and a close friend's experience that a martial arts family can even save your life. Not trying to be depressing, sorry about that

Like a black belt friend of mine says, "A black belt is a white belt that never quit."
So congratulations on your new rank, and good luck as the testing requirements get tougher.
By the way, what type of martial arts is it? I'm in Tang Soo Do, which is similar to Taekwondo. Just curious.
