cant 100% take credit, read this on pinterest years ago.
when you start a journal, get a photo of you with the journal (I use instax photos but you can use the canon printer or print the photo etc) and paste it onto the first page, before the ruled lines. then when you finish the journal, take another photo with the journal and paste it on the last page. it’s a snapshot of you and your words at the beginning and end of its journey :)
