Heh, I'm personally interested in a slightly different question: have any books actually, really made an impact on your startup endeavors? I suppose I'm jaded at this point, but having read so many books whose takeaways can be easily summarized in 4-5 sentences, and with so much advice either very obvious, very difficult, very dependent on specific circumstances and situation, I no longer believe in the value of business/entrepreneurship texts. (massive spoilers: talk to customers early, build your product quickly, get feedback often, make decisions quickly, raise more money than you think you need, when you become CEO your job duties will be very different than what you might expect, build something people love (genius-level advice), ...)
