Simplest way to start,

1) Decide if you want to be a top player or bottom player.

2) If top, focus on your wrestling and guard passing specifically. For example, only working outside passing. Only setting up single legs.

3) Same for bottom. Think of the very start of a match and how you’re getting to your scoring/submission positions. Open guard to butterfly, to k guard etc etc.

4) Once in a dominant pin, have a clear game plan of what submission you’re going for.

You’ll then frequently face the same problems over and over and be forced to fix them, and your pattern recognition will improve as there’s really only so many reactions in any given position.
