Personally I have a text file and the root of every project. Sometimes it's an actual list of things that need to be done still, then a line of hyphens, and the stuff I have cut and pasted below it having done them. If I want to write myself a sentence that I will read first the next time I open the project, it's just the top line in the text file.
This works with so many types of projects. Breadcrumbs to pick it back up...
