try to learn something new. Depending on where you are in your grappling journey, sometimes it may be a new move you've never seen. Other times it may be learning to place your foot two inches to the left and suddenly the move works. It may be something big or very very small (but very important). You can learn something every time you get on the mat and train.
NOTE TO ED: Imagine being a young (per)son rolling with a woman that's old enough to be your...MOM!!! GULP!!!! :D
