3. Out of the Crisis by W. Edwards Deming
Recommended by. . . Jim Koch, founder of Boston Beer Co. (Sam Adams): "It focuses on how you treat people. One of the main points is driving out fear. As a former mountain climber, that resonated. Until you drive out fear, your mind can't focus on making clear, good decisions."

5. The Elements of Style by William Strunk Jr. and E. B. White Recommended by. . . Brian Sharples, co-founder of HomeAway: "Being able to communicate well, especially as an entrepreneur, is hugely important. So much of life is about writing, whether it's email communication, presentations, business plans. I see so many people who can’t write well and when people don’t understand your ideas they can’t go along with them. This is probably the most influential book I've ever read."
