I would as soon leave my son a curse as the almighty dollar.

He that cannot reason is a fool. He that will not is a bigot. He that dare not is a slave.

Every act you have ever performed since the day you were born was performed because you wanted something.

Do your duty and a little more and the future will take care of itself.

Concentration is my motto - first honesty, then industry, then concentration.

Concentrate your energies, your thoughts and your capital. The wise man puts all his eggs in one basket and watches the basket.

No man will make a great leader who wants to do it all himself or get all the credit for doing it.

Think of yourself as on the threshold of unparalleled success. A whole, clear, glorious life lies before you. Achieve! Achieve!
