How Leaders inspire...why the great ones succeed

Why is that only some of the great ones succeed and many other experts fail? It's because they do not understand WHY they are doing things. They know what they are doing, how they are doing, and often the results of what they are doing, but rarely why! Focus on your meaning and your intentions and how you see yourself changing the world, and the rest is easy.
