Start from a blank patch, nothing patched. Then patch your initial idea: what do you want to try or learn, what module do you want to explore? This could be something obvious like a basic technique, it could also be something complex or abstract. Stay with that initial thought.
When you think you're finished, record the patch, power off your system and unplug everything. Next session: do the same. Not only will you be able to learn your system better, you'll also have a collection of your own recordings.
