You must do it alone. - Theodore Roosevelt

With self discipline most anything is possible.

It is no use to preach to [children] if you do not act decently yourself.

I believe in shaping the ends of government to protect property as well as human welfare. Normally, and in the long run, the ends are the same; but whenever the alternative must be faced, I am for men and not for property, as you were in the Civil War. I am far from underestimating the importance of dividends; but I rank dividends below human character. Again, I do not have any sympathy with the reformer who says he does not care for dividends. Of course, economic welfare is necessary, for a man must pull his own weight and be able to support his family. I know well that the reformers must not bring upon the people economic ruin, or the reforms themselves will go down in the ruin. But we must be ready to face temporary disaster, whether or not brought on by those who will war against us to the knife. Those who oppose reform will do well to remember that ruin in its worst form is inevitable if our national life brings us nothing better than swollen fortunes for the few and the triumph in both politics and business of a sordid and selfish materialism.
