Marcelo shares insight on what it takes to reach the goal of black belt: Time on the mat is one of the biggest factors that determines one's promotion to their next belt level. It takes years of cultivating self-discipline and exhibiting respect for one another. Vigilantly attend not only to your own personal temperament, but also toward ways in which you can help raise the level of learning and development for everyone else you share your time with on the mat. Everyone's path is unique, and improvements can be made in small increments or in great bounds. It all can depend on what you have to offer others, and giving back to your community without necessarily expecting something back in return; i.e. doing it for the sake and love of the art itself. Learning never stops, and everyone has valuable knowledge to share regardless of belt color. Keep an attitude of humility, and constantly look to improve everything you do.
