I think if owned one of those beauties, I would get it safe in a safe (is this correct to say).
That being said, in my earlier angst years (pre-teen and teen), I did a lot of writing, tons of it. I would give away my poem collections because I felt keeping them was pointless.
Fun fact one of my teenage love flings, who is my good friend now, confessed to me about a month ago she's kept all my letters. Even sent a picture of the stack. It blew my mind a little bit, and she didn't mean anything by it that could remotely be interpreted as a romantic probe. She's happily married and so am I.
I find the idea of having a place to sit down and let your thoughts pour out very valuable. Moments of honest introspection.
