Man, I needed this video when I was a beginner in Bjj. Maybe I could have avoided the pitfalls of early training, and the self doubt that held back my personal development. And wow at using 60% of your energy when you roll regardless of who you're rolling against. Again, wish I would have thought of that as a beginner, because there were times I was actually afraid to roll because I would expend so much energy trying to win instead of trying to learn. As I got more advanced I used less energy against less experienced opponents, but thinking about it, I wish I had dialed things back from the beginning and just enjoyed the roll instead of always trying to "win" the roll.
