"As important as your words are in shaping your behavior, they are even more important in the way they shape the behavior of others. Your manner of speaking is, if nothing else, the central factor upon which people form assumptions about you. Whatever is your ultimate goal in life, chances are good you're going to have to talk your way to it. And if greatness is your goal, well-spoken words are essential. Think about it. From Homer to Hemingway, Lincoln, Churchill, King, and both Obamas - their words are why we know them."
