Just came across a simplified idea for quick notetaking – bullet journal.
The idea is that you get to write down the important stuff quickly, old style, pen and paper (journal). Full of simple ideas. I guess even taking on board the odd one or two would improve ordering info. Or at least kill the terror of the blank white page in a new diary.
See for yourself. Perhaps it’s a useful starting point you can customize – a cartoonist did some funky drawings in hers – or if you are a list-person anyhow, this may be grist to your mill.
