I have a single system that I use for both digital and paper notes. Start writing, put new stuff at the end. Date every entry. Use topic headings that stand out clearly from the text. When it gets too full, slap a date on the file / notebook and open a new one.
Mostly this is not for returning to, but for thinking things through, although the paper system is also good for to do lists.
Nice. I followed this process of appending the date instead of new notes (or pages) because the paper is too costly. I fell in love with the Midori MD Notebook. I do not want to waste space on the paper, and hence keep appending new notes.
Btw, try out those translucent sticky notes for the highlights.
That is a great notebook; I agree that it’s too fine to leave pages unwritten. The only time I do that is when I change jobs. I’ll have to search up those sticky notes; I didn’t know they existed!
There are a lots of them. I got mine from Amazon. I usually go to JetPens[1] to do the research. I usually tend to start with the Japanese ones.
I’ve been writing (pen-paper) to my daughters on a Notebook. Not a secret. Kept on my desk and besides me, they also love reading the notes. I use a such stickies to highlight interesting ones that I go back and re-read them more often than the other notes.
I suggest writing by addressing to a stranger, the future-you, and I’m very confident those stickies will help. :-)
