We can do only what we think we can do. We can be only what we think we can be. We can have only what we think we can have. What we do, what we are, what we have, all depend upon what we think.

The source and center of all man's creative power... is his power of making images, or the power of imagination.

It is only when you despair of all ordinary means, it is only when you convince it that it must help you or you perish, that the seed of life in you bestirs itself to provide a new resource.

All riches have their origin in mind. Wealth is in ideas - not money.

Before you put pen to paper, before you ring for your stenographer, decide in your own mind what effect you want to produce on your reader — what feeling you must arouse in him.

In every adversity there lies the seed of an equivalent advantage. In every defeat is a lesson showing you how to win the victory next time. [But you must know enough to realise this, lest you focus more on the defeat than finding the lesson you paid for with the defeat. With every defeat and mistake, you have the logical right to get excited about the future when you will understand and be able to apply the lessons and thereby turn defeat and temporary failure into victory and permanent success.]

The great thing is the start - to see an opportunity for service, and to start doing it, even though in the beginning you serve but a single customer - and him for nothing.
