Leaving Microsoft to Change the World, by John Wood, is an inspiration.
Great read. It's the story of a guy who decides to quit his current life, job and girlfriend, to live a life of purpose. We love "real life" stories and this one is amazing. You'll be blown away at the huge risks he takes to chase his passion of helping kids in Nepal and creates an amazing organization built on "purpose" in the process. Brilliant and inspirational.
