bjj tips

Hey all, Im looking at doing some one on one BJJ sessions to help me improve a bit more separate to doing the classes. Some things I already know I want to work on are improving my hip escapes from the bottom but would you say there is any other key things to focus on during that one on one...

I've been training in BJJ for a while. I love reading stuff from the BJJ guru, I learn lots of cool stuff. I was wondering where you guys are reading? And which sites can help me improve my grappling techniques? Videos on YT are helpful but I think I obsessively went through all of them already...
