The essential element in personal magnetism is a consuming sincerity - an overwhelming faith in the importance of the work one has to do.

Action and reaction, ebb and flow, trial and error, change - this is the rhythm of living. Out of our over-confidence, fear; out of our fear, clearer vision, fresh hope. And out of hope, progress.

When you're through changing you're through.

Every time you open your mouth you let men look into your mind.

Most successful men have not achieved their distinction by having some new talent or opportunity that was at hand.

When you can dump a load of bricks on a corner lot, and let me watch them arrange themselves into a house - when you can empty a handful of springs and wheels and screws on my desk, and let me see them gather themselves together into a watch - it will be easier for me to believe that all these thousands of worlds could have been created, balanced, and set to moving in their separate orbits, all without any directing intelligence at all.

If advertising encourages people to live beyond their means, so does matrimony.
