You are now, and you do become, what you think about.

Get into a line that you will find to be a deep personal interest, something you really enjoy spending twelve to fifteen hours a day working at, and the rest of the time thinking about.

Your rewards will be determined by the extent of your contribution, that is your service to others.

It is in the expectations of happiness that much of happiness itself is found. And it takes courage to expect happiness.

Everything that's really worthwhile in life came to us free - our minds, our souls, our bodies, our hopes, our dreams, our ambitions, our intelligence, our love of family and children and friends and country.

Every one of us is the sum total of his own thoughts

A single thought can revolutionize your life as it did mine. A single thought can make you rich or it can land you in prison for the rest of your life.
