"You can’t let your failures define you. You have to let your failures teach you."
"Evil does exist in the world. A non-violent movement could not have halted Hitler's armies. Negotiations cannot convince al Qaeda's leaders to lay down their arms.

"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."
"The best way to not feel hopeless is to get up and do something. Don’t wait for good things to happen to you. If you go out and make some good things happen, you will fill the world with hope, you will fill yourself with hope."
"Just because we have the best hammer does not mean that every problem is a nail."
