I can't train full time. I train Mon-Sat about two hours a day, I just drill a LOT. I warm up with armbars, triangles, and kimuras every day. Black belt or not (JC that's weird to say), you need to do them. And I train with my boys, who know how to kill my guard like no other so I have to open up and try new things. I study 8-4 usually so only one training session a day. Breaks of any kind I travel to get new training partners (mock competitions with more mat time, essentially. This is VERY important to learn your holes) and train 2-3 times a day.
Every 3-4 months I have a mental/physical breakdown from everything. I spend a day on the couch eating ice cream and watching South Park. The next day I feel awesome.
