If you were a BJJ black belt and you were also a Millionaire...meaning you had more money than you could spend. Would you teach people BJJ for free or would you still charge? I personally would buy a building and set it up for teaching BJJ. I then would teach BJJ for free to anyone, especially our youth, who is willing to work hard and give back to the community. Hey you only live once and we are being judged for our actions in this life time.
