Over the past 10 years I've found that their are several books that I continue to go back to over and over for advise. Below is a photo of the top books that I think every filmmaker should own. Out of all the books some cinema books now don't get used as much these days with Youtube but they are still helpful. Below is a list of business books that I think are the most important.
The Art of the Start by Guy Kawasaki. Amazon
Let my people go surfing by Yvon Chouinard. Amazon
Story by Robert McKEE, Best book I have on Story. Amazon
From Reel to Deel by Dov S-S Simens. The one book that puts all of filmmaking in cliff notes and is extremely entertaining! Amazon
Producing with Passion: Making Films That Change the World. One of the best books I have on creating films for social change. Amazon
The Purpose Driven Life by Rick Warren. I've found this book is good for the soul. Amazon
The rest of the book are worth a look.
