What is the biggest pieces of advice and coach/training partner gave you that made a difference in your game?  I have many, but first one that comes to mind was from an upper belt training partner.  I think about low-mid blue, I was having a hard time getting better and how to escape from side control, especially against the bigger opponents.  I was told to take two months and just start every round from bottom side and get as many reps as you can.  He said he did they same thing and you just needs the reps to build the escapes/frames/movement/calm needed when being smashed.  I use this method a lot and still to this day when trying to new things and just commit to a time period to work on them.
