"My main purpose in life is to..." - Quote by Thomas Edison

“What you are will show in what you do.”

“Being busy does not always mean real work. The object of all work is production or accomplishment and to either of these ends there must be forethought, system, planning, intelligence, and honest purpose, as well as perspiration. Seeming to do is not doing.”

“I think work is the world's greatest fun.”

“Career is the stringing together of opportunities and jobs. Mix in public opinion and past regrets. Add a dash of future panic and a whole lot of financial uncertainty. Career is something that fools you into thinking you are in control and then takes pleasure in reminding you that you aren't. Career is the thing that will not fill you up and will never make you truly whole.”

“The single most important thing to remember about any enterprise is that there are no results inside its walls. The result of a business is a satisfied customer.”

“Happiness is the utilization of one's talents along lines of excellence.”

“In whatever system where the weight attached to the wheel should be the cause of motion of the wheel, without any doubt the center of the gravity of the weight will stop beneath the center of its axle. No instrument devised by human ingenuity, which turns with its wheel, can remedy this effect. Oh, speculators about perpetual motion, how many vain chimeras have you created in the like quest. Go and take you place with the seekers after gold.”

“I'm one of those people that think Thomas Edison and the light bulb changed the world more than Karl Marx ever did.”

“At the Egyptian city of Naucratis there was a famous old god whose name was Theuth; the bird which is called the Ibis was sacred to him, and he was the inventor of many arts, such as arithmetic and calculation and geometry and astronomy and draughts and dice, but his great discovery was the use of letters.”
