I've been doing one of those special regimens to help you organize your thoughts and improve your memory and so on. Each thought and memory is associated with a particular location in a grand palace, based on the overall topic.
From there, thoughts are divided into colors. Long strings to memorize (like quotes and phone numbers) are blue, for instance, and emotional memories are light brown. Methods or orders of operation are purple, reminders to do things are green, stories yellow, and mistakes that I want to avoid repeating are red.
When a thought or memory turns out to be false, you turn it invisible. So, for instance, if someone tells your a phone number, and then tells you a new phone number, the old one fades to transparent.
The problem I'm having is this: sometimes I'll get a reminder of something I need to do, like "check that the stove is off" or "wash my hands", and it will keep nagging me even when I'm done. I try to turn those obsessive thoughts transparent, and they go temporarily dormant, but I can feel an anger building up in me as I try to suppress my obsessive-compulsive behavior. Colorless green ideas sleep furiously.
