Thought is the wind, knowledge the sail, and mankind the vessel.

Every heart that has beat strongly and cheerfully has left a hopeful impulse behind it in the world, and bettered the tradition of mankind.

Health is the greatest possession. Contentment is the greatest treasure. Confidence is the greatest friend. Non-being is the greatest joy.

Wonder rather than doubt is the root of all knowledge.

I can't change the direction of the wind, but I can adjust my sails to always reach my destination.

It is in your moments of decision that your destiny is shaped.

The glow of one warm thought is to me worth more than money.

Only those who have learned the power of sincere and selfless contribution experience life's deepest joy: true fulfillment.

I've been absolutely terrified every moment of my life - and I've never let it keep me from doing a single thing I wanted to do.

Everyone here has the sense that right now is one of those moments when we are influencing the future.
