Quote of the day by Al Gore: Al Gore's quote centers on the moment when an interest or concern becomes something a person feels compelled to act on. He describes entering a classroom more than four decades earlier and encountering one of the leading scientists in the field, an experience that helped turn an intellectual interest into a long-term public cause. The important point is not simply that he became passionate about an issue, but that meaningful work can begin with an ordinary encounter that changes how a person sees a problem.
