Our mental make-up is suited to a life of very severe physical labor

No great achievement is possible without persistent work.

The world that we must seek is a world in which the creative spirit is alive, in which life is an adventure full of joy and hope, based rather upon the impulse to construct than upon the desire to retain what we possess or to seize what is possessed by others.

It is only through labor and painful effort, by grim energy and resolute courage, that we move on to better things
