Permission Marketing - Seth Godin, made me think about what he calls interruption marketing. Purple Cow - Seth Godin, made me think about standing out. The Lean Startup - Eric Ries, really changed the way I think about... Well, nearly everything that costs effort. The God Delusion - Richard Dawkins, good theory about why God most probably doesn't exist. The magic of reality - Richard Dawkins, great story about evolution, religion, etc. A short history of nearly everything - Bill Bryson, brilliant book. Perfect summary of our scientific advancements during the last centuries. He made me think about possible natural disasters.
