Iām interested in hearing how others deal with quotes as well. I started by having one quote per note but have recently started organizing them by category.
I keep quotes in separate notes by type. For example I have a note for all the silly things my partner says with the tag #personal/family. I also have a note containing all the inspiring quotes I came across in books and Internet but I tagged it as #ideas.
If the quote pertains to a topic, I likely already have a note on that topic, which is where I put the quote. Otherwise, for more general quotes, I maintain a note per person if they have two or more quotes, and a catch-all note for people with only one quote.
