There's nothing wrong with it in general, but for me having the books in my house would make me feel like I have to read all of them asap and would make reading into a chore. For me reading should be about the journey, not the destination.

Personally what I do is, I do have a TBR list on Goodreads, but I usually buy 8-10 books at a time. Then I get new ones when I'm almost done with my 8-10 books. This way there are always unread books on my nightstand to choose from, but I don't have the unread books stacking up and making me feel guilty about not yet reading them.

But if you're a young person looking to fill their first bookshelf, I can imagine how that's different for you!
