Leadership is the art of accomplishing more than the science of management says is possible.

Organization doesn't really accomplish anything. Plans don't accomplish anything, either. Theories of management don't much matter. Endeavors succeed or fail because of the people involved. Only by attracting the best people will you accomplish great deeds.

Too often we act - ask our schools to be truant officers, our teachers to be truant officers, because we're giving them children who have, you know, they're not ready to learn. And if they're not ready to learn by the third grade, they know they're behind.
