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

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

Giving should be entered into in just the same way as investing. Giving is investing.

Never was I power thirsty, or trying to control everyone. I believed in educating everyone, so they could all get to the position I was at.

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

The impression was gaining ground with me that it was a good thing to let the money be my slave and not make myself a slave to money.

Never lose interest in life and the world. Never allow yourself to become annoyed.
