“Question everything—no matter how beloved, or how long-held, or how exalted—without apology. Only those who build their world upon lies need fear an inquisitive mind. The truth will remain, even after a storm of doubt and revolution has washed over it. Only illusions need be protected. The truth need not be defended; it existed before us and will continue to exist after us.”

“You got to insist on your success, resist every obstacle and persist in times of difficulty and you will get there.”

“The only walls that exist are those you have placed in your mind. And whatever obstacles you conceive, exist only because you have forgotten what you have already achieved.”
