Andrew Carnegie said that all success and wealth first starts in your mind:
"The man who acquires the ability to take full possession of his own mind may take possession of anything else to which he is justly entitled."
"Here is the prime condition of success: Concentrate your energy, thought and capital exclusively upon the business in which you are engaged. Having begun on one line, resolve to fight it out on that line, to lead in it, adopt every improvement, have the best machinery, and know the most about it."
"Concentrate your energies, your thoughts and your capital. The wise man puts all his eggs in one basket and watches the basket."
"Think of yourself as on the threshold of unparalleled success. A whole, clear, glorious life lies before you. Achieve! Achieve!"
Henry Ford said that all success and wealth first starts in your mind:
"You must never, even for a second, let yourself think that you can fail. Our first principle is that failure is impossible. If you shut out of your mind the possibility of being licked, then you are bound to win."
"One who fears the future, who fears failure, limits his activities. Failure is only the opportunity more intelligently to begin again. There is no disgrace in honest failure; there is disgrace in fearing to fail."
"Thinking is the hardest work any one can do, which is probably the reason why we have so few thinkers."
"If money is your hope for independence you will never have it. The only real security that a man will have in this world is a reserve of knowledge, experience, and ability."
