Keeping a pocket notebook from becoming a second planner

[joanna_k]

I like the idea of carrying a small notebook, but I overthink what to put in it, and it starts to feel like another planner I have to maintain. My plan is to use it for quick things I need while I'm out—an address or something to pick up—then transfer any notes that still matter to the right place later. Does anyone use a simpler rule for deciding what belongs in a pocket notebook?

I decide based on whether I'd be annoyed if I forgot it before I could get to my usual system. If I would, I jot it down; otherwise, it can wait. I don't count on checking the pocket notebook every day.
