You have to find what sparks a light in you so that you in your own way can illuminate the world.

If you're changing the world, you're working on important things. You're excited to get up in the morning.

Every generation has its defining works. More than 300,000 people worked to put a man on the moon - including that janitor. Millions of volunteers immunized children around the world against polio. Millions of more people built the Hoover dam and other great projects. These projects didn't just provide purpose for the people doing those jobs, they gave our whole country a sense of pride that we could do great things.

Have you grasped nothing of the reason why I am in the world?

What you want, what you're hanging around in the world waiting for, is for something to occur to you.

We must know that we have been created for greater things, not just to be a number in the world, not just to go for diplomas and degrees, this work and that work. We have been created in order to love and to be loved.
