We are always creating new tools and techniques to help people, but the fundamental framework is remarkably resilient, which means it must have something to do with the nature of organizations or human nature.

If we live a self-directed, self-motivated, self-centered life, always needing to get our own way, then we're going to be miserable. In fact, many times we believe it's our problems that are making us unhappy when, in reality, it's because we're focused on ourselves!
