Over beach vacation last week, I hijacked my dad's copy of Delivering Happiness: A Path to Profits, Passion, and Purpose by Tony Hsieh, CEO of Zappos.com. You may have heard about it on NPR. Hsieh built and sold a company right out of college and, with the proceeds, as well as a venture fund he raised called Venture Frogs, did some early stage investing. Hsieh ended up investing in, and later helping to build, Zappos.com as CEO.
