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

“The three things that are most essential to achievement are common sense, hard work and stick-to-it-iv-ness... Unfortunately, many of life's failures are experienced by people who did not realize how close they were to success when they gave up. I have far more respect for the person with a single idea who gets there than for the person with a thousand ideas who does nothing.”

“The biggest failure of man is that he gives up before he realizes how close he was to success.”

“After we had conducted thousands of experiments on a certain project without solving the problem, one of my associates, after we had conducted the crowning experiment and it had proved a failure, expressed discouragement and disgust over our having failed to find out anything. I cheerily assured him that we had learned something. For we had learned for a certainty that the thing couldnt be done that way, and that we would have to try some other way.”

“For what are we born if not to aid one another?”

“The greater part of all the mischief in the world arises from the fact that men do not sufficiently understand their own aims.”

“Hustle is waking up the day before you die and realising you gave it your all.”

“I have no private interest in the reception of my inventions by the world, having never made, nor proposed to make, the least profit by any of them.”

“The martini: the only American invention as perfect as the sonnet.”

“The most amazing and effective inventions are not those which do most honour to the human genius.”
