We cannot meet 21st Century challenges with a 20th Century bureaucracy.

You can’t let your failures define you. You have to let your failures teach you.

Change will not come if we wait for some other person or some other time. We are the ones we've been waiting for. We are the change that we seek.

Keep exploring. Keep dreaming. Keep asking why. Don’t settle for what you already know. Never stop believing in the power of your ideas, your imagination, your hard work to change the world.

When ignorant folks want to advertise their ignorance, you don't really have to do anything, you just let them talk.
