"You don't need to be the smartest person to be the most effective. Being effective means not just mastering the facts but – figuring out how to move your agenda forward... Change happens only when you could educate and inspire others. When you could use facts to create faith in what's possible... The easy part will be to write papers for your peers... The harder part, and the one you should think about, is how are you going to explain inconvenient truths to people who may not want to hear them. How are you going to rouse an audience to action?...The measure of a life is not time or money. It’s the impact you make serving God, your family, community, and country. Your report card is whether you leave the world a better place."
