@kaa oh boy is this a hard one, I personally keep all my A6 notebooks because I keep all my thoughts and journal in them. However Field Notes are harder, most are filled with shopping list and random numbers and things I jotted down, but on some random page is a note about my mother’s passing. So do I keep that whole note book for that one page or throw it out and lose that moment. Yeah I realize this is not helping but I sympathize with your problem so much
