I've been reading a lot of books this year, however, not all of them have been insightful. A hack I found is to google "<Author's name> quotes" and see if they've come up with interesting stuff before engaging in the author's book. Reading someone's quotes (especially a philosopher) is like watching an MMA fighter's highlights. You get a very good idea whether you should pursue their books or pass. This ends up saving me a lot of time in picking the right authors and books.
