I've listened to a few books this year (Audible saves me time), but I read/listened to a book that actually changed my life in the summer of 2012 (close enough). I had wanted to become an entrepreneur, but then I read The Millionaire Fastlane by MJ DeMarco. He described some of the things that I really don't want to do deal with: hiring non-engineer employees, using the services of lawyers, marketing, and other business responsibilities. It wasn't that I hadn't heard these themes before, but he said it in a way that made me recognize what I don't want. I just want to be a great engineer. I didn't give up on a dream; I found a better one.
