You do ill if you praise, but worse if you censure, what you do not understand.

Do what thy manhood bids thee do, from none but self expect applause; He noblest lives and noblest dies who makes and keeps his self-made laws.

Fools rush in where fools have been before.

Whenever you commend, add your reasons for doing so; it is this which distinguishes the approbation of a man of sense from the flattery of sycophants and admiration of fools.

Far better to think historically, to remember the lessons of the past. Thus, far better to conceive of power as consisting in part of the knowledge of when not to use all the power you have. Far better to be one who knows that if you reserve the power not to use all your power, you will lead others far more successfully and well.

Let not thy will roar, when thy power can but whisper.

The great secret of power is never to will to do more than you can accomplish.

The secret of all power is - save your force. If you want high pressure you must choke off waste.

The most important thing in life is to see to it that you are never beaten.

They can do all because they think they can.
