Once we are destined to live out our lives in the prison of our mind, our duty is to furnish it well.

Pep without purpose is piffle.

A purpose you impart is no longer your own.

Ordinary people think merely of spending time. Great people think of using it.

If we don't stand for something, we may fall for anything.

This is the true joy in life, the being used for a purpose recognized by yourself as a mighty one; the being thoroughly worn out before you are thrown on the scrap heap; the being a force of nature instead of a feverish selfish little clod of ailments and grievances complaining that the world will not devote itself to making you happy.

Battle doesn't need a purpose; the battle is its own purpose.

The one who adapts his policy to the times prospers, and likewise that the one whose policy clashes with the demands of the times does not.

It is your work in life that is your ultimate seduction.

Our chief usefulness to humanity rests on our combining power with high purpose. Power undirected by high purpose spells calamity, and high purpose by itself is utterly useless if the power to put it into effect is lacking.
