Follow the traditional Jiu-jitsu of Grand Master Hélio Gracie, always be oriented to submissions, always aim to prove the technical efficiency.

This spirit cannot die.
There are lots of people that only care about winning and sometimes forget that the ultimate performance is to bring all your weaponry to the match and prove the efficiency of BJJ. In the end you are not the winner, jiu-jitsu is.
If you fight with the right spirit, even if you lose the match, but placed all your knowledge in the fight you are always a winner.
