Vengeance is the most costly and dissipating of luxuries.

Duty and prudence alike command, first, that the germ-centres of hatred and revenge should be constantly and vigilantly surveyed and treated in good time, and, secondly, that an adequate organisation should be set up to make sure that the pestilence can be controlled at its earliest beginnings before it spreads and rages throughout the entire earth.

Always stay gracious, best revenge is your paper.

If you will not fight for right when you can easily win without bloodshed; if you will not fight when your victory will be sure and not too costly; you may come to the moment when you will have to fight with all odds against you and only a precarious chance of survival.

No folly is more costly than the folly of intolerant idealism.

A politician needs the ability to foretell what is going to happen tomorrow, next week, next month, and next year. And to have the ability afterwards to explain why it didn't happen.
