People are happiest in a job they find worthwhile. In fact, people often work harder for fewer rewards for causes linked to deep belief.—Stever Robbins
Belief is an important component to success. HBS Working Knowledge has a great article about the role of belief in success. This is something that I haven’t felt since working at Trilogy or Reactivity, both of these companies made me believe that I was making a difference. Charismatic leaders like Steve Jobs, Clarence "Kelly" Johnson and others, are able to convince those that work with them of the vision and its importance.
