Navigating the world of Sociology is murky. We want to know group behavior and how the world functions. Yet research often shows moderately reliable data that often gets expressed incorrectly as hard facts. Add that to a market of people trying to find answers in a book, we are now at the massive money-making world of Self-Help books. While I support people reading Top-Sellers and books I like, I really encourage everyone to be hypercritical of these books. Be skeptical. And don't take them to be 100% fact. With that said, there is an author I like. I would ask everyone to read his work and debate with me on his points. If not for that, just simply read it because his work is brought up in businesses all the time. Here is a great speech from Daniel Goleman at Google Inc. discussing his concept of emotional intelligence.
