I never placed my head upon the pillow at night without reminding myself that my success might only be temporary.

I have ways of making money that you know nothing of.

Get rich by taking something common and making it uncommon.

Be sure that you are not deceiving yourself at any time about actual conditions.

Every right implies a responsibility; Every opportunity, an obligation, Every possession, a duty.

It has always been my rule in business to make everything count.

The secret of success is to get up early, work late and strike oil.
