Big gains in sparring development. The gains were NOT submissions, but defense from not being tapped out as often as previous sessions. I would say the development has to do with the advanced grappling class. When an opponent had me mounted and had their knees in the arm pits, I was able to shrimp out in order to get my elbows back down on the floor. Last time I sparred, I was tapped out a lot of times with the arm bar. Also, I learned a technique, from advanced grappling, to keep the elbows together on the chest and hands on the chin. That technique stopped multiple choke attacks.
This week I took the Advanced class which was taught by Professor Gui. During sparring, I was able to use the lesson on arm bar breaks to get a submission.
Back to fundamentals. I bought a new notebook. I plan to combine the notes from two other notebooks with the current lesson. I was trying to make a mnemonic device to help remember each lesson. I think this is the path to mastery. I believe I could get more out of my class time if I become more mindful. Mindful, being more focused, looking for details that I may have missed during previous lessons.

A wise idea. Take notes. Review your notes before going to bed. The reason, we tend to remember things we review before going to sleep. It is how the mind works.
