Roy Harris: Refine. Focus. Define.

From Roy Harris' great essay, "Progression in Brazilian Jiu Jitsu"

Once a student has a firm grip on the mastery of his basics, I will promote him to brown belt. Once he has been promoted to brown belt, he must continue to refine his game. He must seek out his weak areas and focus on them. He must also find his strengths and focus on them for an extended period of time because these will define his character as a black belt. Most black belts have a specialty. Some are good at throws. Others are good at collar chokes. I happen to be good at leg locks. I want my brown belts to find their sweet spot and train it like crazy!
