Ultimately, you just have one life. You never know unless you try. And you never get anywhere unless you ask.

Don’t worry about failure; you only have to be right once.

Thousands of candles can be lighted from a single candle. Happiness never decreases by being shared.

It is not the strongest of the species that survive, nor the most intelligent, but the one most responsive to change.

If there is no struggle, there is no progress.

When the pressure is on, you don’t rise to the occasion - you fall to your highest level of preparation.

Give me a place to stand, and a lever long enough, and I will move the world.
