Journals don't have to be personal to the point where they're hard to share. They can be like schedule planners, or just picture books, or even for writing quotes.

So here's one thing I'm doing when I get a journal;
Write down something personal on a full page, then glue a picture over it
like so

aesthetic and journal image

Its one way to let go, the picture reminds you that it's still there, and its covering your feelings to remind you to let it go.
