Honestly, I'm not sure I get why this guy is considered one of the all-time great lecturers. He never seems to explain something in 5 minutes when he could do it in 15.
I'm currently refreshing myself on linear algebra by going through his book and video lectures. It's making a lot more sense to me this time around. I think watching him go through his thought process on the board cements the reasoning in my head, rather than just memorizing the shortcuts leading to an answer.
