“Keep away from people who try to belittle your ambitions. Small people always do that, but the really great make you feel that you, too, can become great.”

Success is not final; failure is not fatal: It is the courage to continue that counts.

I believe in being an innovator.

In life, unlike chess, the game continues after checkmate.

I prefer to be true to myself, even at the hazard of incurring the ridicule of others, rather than to be false, and to incur my own abhorrence.

We could never learn to be brave and patient if there were only joy in the world.

Nothing could be worse than the fear that one had given up too soon, and left one unexpended effort that might have saved the world.
