Earnestness is enthusiasm tempered by reason.

We are so presumptuous that we should like to be known all over the world, even by people who will only come when we are no more. Such is our vanity that the good opinion of half a dozen of the people around us gives us pleasure and satisfaction.

This is the motive of every action of every man, even of those who hang themselves.
