Surprised nobody has mentioned it yet, but… If you’re trying to hold your unfinished work in your head, then it’ll hound you whenever you aren’t working. So get it out of your head. Write it down.

Just mind dump into a text file or email to yourself or calendar event (for Monday morning) or sticky note or whatever works for you. Get down everything you can think of that’ll need your attention the next time you’re working.

Then, forget about it. Now that you have it captured somewhere, you can stop thinking about it until Monday morning or whatever. If you didn’t capture it, your brain won’t let you stop thinking about it. But now, present you knows that past you has teed things up for future you, so there’s no need to remain preoccupied.

You’ll know right away if this approach is right for you. If you feel a sense of relief after getting your mind dump out, then you’re onto something.
