Try it out with a book that isn't your #1 favourite. See how it looks after and if you're ok with your books looking like that.
I carry round my books to read and they are all a little banged up after. I don't mind though, they just looked loved and appreciated.
Sometime in the past i made the decision that I would bring a book anywhere I felt like reading. Short possibly relevant anecdotal story: So I travaled an camped with some friends for a few days close to waterfall, I would wake up before everyone else, and have 2 hours for me, to read. But you can imagine the situation with a bunch of early 20s in the middle of nowhere with alot of booze is not quite heathy for the book wellbeing, alots of beer spilled. I finished the book on our 3 hour trip back home and it felt amazing, my trip was amazing and I was happy I brought that book, even thought it took a big hit on his apearece, but I feel good when I look at it. So yeah, there are books I read snaking popcorn, for me, the value of the moment is worth more than the book wellbeing. ( Of course that doesn't mean I'll have all my books gross)
