Quality matters more than quantity. There's no point in reading loads of books in a short amount of time but couldn't recall enough about what the books say.
Book summary services don't really resemble the actual books. Those summaries are useful as a stepping stone for us to explore more from the books. For me myself, I just basically use them as some kind of trailer of the books before I buy them, just to make sure I really want to read those books.
We don't have to read books that we find boring. We don't always have to finisih the book we already started if it doesn't suits us.
