Engineering Your Path to Joy. This is a startling original book about creating and maintaining happiness, written by a top Google executive with an engineer's training and fondness for thoroughly analyzing a problem. In 2001, Mo Gawdat, a remarkable thinker whose gifts had landed him top positions in half a dozen companies and who in his spare time had created significant wealth, realised that he was desperately unhappy.
