An abundance of new research suggests that longevity is not only about good genetics and clean living. Other variables like exercise, meditation, volunteering, and close friendships are also linked to extending your visit here on planet Earth. But more recent findings have revealed that passion -- having a cause, purpose or pursuit -- can also contribute to an increase in longevity.

As a psychologist, I was fairly sure I knew what characteristics define successful people. Don't we all? I mean, successful people are confident, ambitious, risk-takers who persevere in the midst of setbacks and challenges. But, just to be sure, I decided to do some research into the characteristics of successful people. What I gleaned from my efforts is this: 1) many successful people write lists of characteristics of successful people, 2) nobody's list looks anything like anybody else's list and 3) therefore, each list of characteristics of successful people is probably nothing more than a flattering self-portrait of the writers themselves.
