Take notes, on your computer. Keep the notes in one place (at least for each topic). I don't have enough memory to keep track of everything on my project at work. There's too many loose ends. There would still be too many loose ends if I had a better memory, too (for any realistic value of "better"). So I keep all that in a file of notes about the project, and keep it updated as things change. Ctrl-f beats any memory trick ever invented.
