"The trouble with most people is that..." - Quote by Thomas Edison

“I know of over 3,000 ways [that] a light bulb does not work.”

“Consider data without prejudice.”

“I speak without exaggeration when I say that I have constructed 3,000 different theories in connection with the electric light, each one of them reasonable and apparently likely to be true. Yet only in two cases did my experiments prove the truth of my theory. My chief difficulty was in constructing the carbon filament... Every quarter of the globe was ransacked by my agents, and all sorts of the queerest materials used, until finally the shred of bamboo, now utilized by us, was settled upon.”

“Man will occasionally stumble over the truth, but most of the time he will pick himself up and continue on.”

“You cannot give up - you have to be persistent and keep pushing, and press on.”

“Here is a commandment for you: seek happiness in sorrow. Work, work tirelessly.”

“I wonder how many times people give up just before a breakthrough - when they are on the very brink of success.”

“Of course motivation is not permanent. But then, neither is bathing; but it is something you should do on a regular basis.”

“I'm a success today because I had a friend who believed in me and I didn't have the heart to let him down.”
