We should so live and labor in our times that what came to us as seed may go to the next generation as blossom, and what came to us as blossom may go to them as fruit. This expresses the true spirit in the love of mankind.

No great achievement is possible without persistent work.

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

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

The highest pleasure to be got out of freedom, and having nothing to do, is labor

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.
