Once I realised I rarely read my notes, I now put them in a single note and prepend it when I add something new. It’s weird but I think the value I get from notes is in the writing of them, it’s a way of thinking rather than for recall.
It really is in the writing and not the referencing 95% of the time. That's why I tend to hand-write my notes. If it 's something I think I should have for reference, I'll transcribe, bookmark a reference, or something.
