America was not built on fear. America was built on courage, on imagination and an unbeatable determination to do the job at hand.

You must never be fearful about what you are doing when it is right.

If a man will begin with certainties, he shall end in doubts; but if he will be content to begin with doubts he shall end in certainties.

What though strength fails? Boldness is certain to win praise. In mighty enterprises, it is enough to have had the determination.

The individual has always had to struggle to keep from being overwhelmed by the tribe. If you try it, you will be lonely often, and sometimes frightened. But no price is too high to pay for the privilege of owning yourself.

But the bravest are surely those who have the clearest vision of what is before them, glory and danger alike, and yet notwithstanding go out to meet it.

The brave person thinks of themselves last of all.

There is nothing more difficult to take in hand, more perilous to conduct, or more uncertain in its success, than to take the lead in the induction of a new order of things.

Let me give you a tip on a clue to men’s characters: the man who damns money has obtained it dishonorably; the man who respects it has earned it.

You will never do anything in this world without courage. It is the greatest quality of the mind next to honor.

Duty, honor, country. Those three hallowed words dictate what you ought to be, what you can be, what you will be.

All the breaks you need in life wait within your imagination, imagination is the workshop of your mind, capable of turning mind energy into accomplishment and wealth.

If you can imagine it you can achieve it. If you can dream it, you can become it.

The heights by great men reached and kept Where not attained by sudden flight, But they, while their companions slept, Were toiling upward in the night.

It may easily come to pass that a vain man may become proud and imagine himself pleasing to all when he is in reality a universal nuisance.

A man, to carry on a successful business, must have imagination. He must see things as in a vision, a dream of the whole thing. A man can cultivate this faculty only by an appreciation for the finer things in life.

Only in men's imagination does every truth find an effective and undeniable existence. Imagination, not invention, is the supreme master of art as of life.

Music gives a soul to the universe, wings to the mind, flight to the imagination and life to everything.

To raise new questions, new possibilities, to regard old problems from a new angle, requires creative imagination and marks real advance in science.
