Previously the majority of the books I read came in the form of cheap ebooks from the Kindle store. As a result, I often abandoned them (or even just forgot about them), only reading a few chapters. Now though, when I spend £30 on a single book, damn right am I going to finish it.
Plus, as a result of the curation, there isn't a single book on their site that isn't at least worth a glance. The same can't be said for many physical bookstores, let alone Amazon, etc.
And, the best part is, I don't really need these expensive books anymore. I've gotten into such a habit of reading because of them that I'm buying regular books again and I'm reading for at least an hour or two a night.
