Or, in other words, how do you pick what to read next?

There are millions of books in existence and only twenty-four hours in the day. I'm curious how everyone here picks what books go on (and, depending on your proclivity for dropping books mid-read, stay on) your reading list?

Librarian recommendations? "Best of" lists? Your favorite authors' latest? Social media recommendations? Whatever seems "hot" at the moment? Serial publications/anthologies? High school/college reading lists*? Covers/titles that entice you? Whatever your approach, I wanna hear it!

*This is a fantastic way of creating non-fiction reading lists, but I can't imagine doing this with fiction--I'm just not that much of a literary masochist.
