Probably a little oversimplified, but I like having models for behavior, most especially my own.
I am in the process of being more generally organized, specifically about time. I may get a lot done in any given day, but if I can't check stuff off a list it can feel like I got nothing done. I have this nasty habit of immediately disregarding a task once I've finished it. As in, completely removing it from my mental map. Being able to plan out exactly when I can address stuff that I might not be able to tackle immediately helps a lot with reducing my 'HOLY SHIT IF I DON'T DO THIS NOW I'LL NEVER DEAL WITH IT' anxiety.
