Theodore Roosevelt

Leave it as it is. The ages have been at work on it and man can only mar it.

When you play, play hard when you work, don’t play at all.

I am only an average man but, by George, I work harder at it than the average man.

It behooves every man to remember that the work of the critic is of altogether secondary importance, and that, in the end, progress is accomplished by the man who does things.

I don’t pity any man who does hard work worth doing. I admire him. I pity the creature who does not work, at whichever end of the social scale he may regard himself as being.

Far and away the best prize that life has to offer is the chance to work hard at work worth doing.
