Tapping into some aggression

Purple belt here. I like to think my game is pretty technical and though I am decently fit and athletic I like a more relaxed, technical roll.

I feel like often I “lose” (there’s no losing in training, but you get the point) to people I feel I’m technically better than because they’re just a bit meaner. Furthermore, I have a hard time finishing athletic lower belts because they explode so much whereas I’m trying to remain technical.

I pride myself on being a good training partner but I think I need to tap into a bit of nastiness and athletic explosion to really utilize my game. Any tips?
