Our greatest weakness lies in giving up. The most certain way to succeed is always to try just one more time.
Thomas A. Edison
Opportunity is missed by most people because it is dressed in overalls and looks like work.
Thomas A. Edison
Many of life's failures are people who did not realize how close they were to success when they gave up.
Thomas A. Edison
Just because something doesn't do what you planned it to do doesn't mean it's useless.
Thomas A. Edison
Waste is worse than loss. The time is coming when every person who lays claim to ability will keep the question of waste before him constantly. The scope of thrift is limitless.
Thomas A. Edison
There will one day spring from the brain of science a machine or force so fearful in its potentialities, so absolutely terrifying, that even man, the fighter, who will dare torture and death in order to inflict torture and death, will be appalled, and so abandon war forever.
Thomas A. Edison
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.
Thomas A. Edison
The doctor of the future will give no medicine but will instruct his patient in the care of the human frame, in diet, and the cause and prevention of disease.
Thomas A. Edison
The three great essentials to achieve anything worth while are: Hard work, Stick-to-itiveness, and Common sense.
Thomas A. Edison
Non-violence leads to the highest ethics, which is the goal of all evolution. Until we stop harming all other living beings, we are still savages.
Thomas A. Edison
Restlessness is discontent and discontent is the first necessity of progress. Show me a thoroughly satisfied man and I will show you a failure.
Thomas A. Edison
I have friends in overalls whose friendship I would not swap for the favor of the kings of the world.
Thomas A. Edison
The reason a lot of people do not recognize opportunity is because it usually goes around wearing overalls looking like hard work.
Thomas A. Edison
I never did anything by accident, nor did any of my inventions come by accident; they came by work.
Thomas A. Edison
Anything that won't sell, I don't want to invent. Its sale is proof of utility, and utility is success.
Thomas A. Edison
Maturity is often more absurd than youth and very frequently is most unjust to youth.
Thomas A. Edison
Be courageous. I have seen many depressions in business. Always America has emerged from these stronger and more prosperous. Be brave as your fathers before you. Have faith! Go forward!
Thomas A. Edison
I find my greatest pleasure, and so my reward, in the work that precedes what the world calls success.
Thomas A. Edison
I know this world is ruled by infinite intelligence. Everything that surrounds us- everything that exists - proves that there are infinite laws behind it. There can be no denying this fact. It is mathematical in its precision.
Thomas A. Edison
Nearly every man who develops an idea works it up to the point where it looks impossible, and then he gets discouraged. That's not the place to become discouraged.
Thomas A. Edison
One might think that the money value of an invention constitutes its reward to the man who loves his work. But... I continue to find my greatest pleasure, and so my reward, in the work that precedes what the world calls success.
Thomas A. Edison
Results! Why, man, I have gotten a lot of results. I know several thousand things that won't work.
Thomas A. Edison
When I have fully decided that a result is worth getting I go ahead of it and make trial after trial until it comes.
Thomas A. Edison
It is astonishing what an effort it seems to be for many people to put their brains definitely and systematically to work.
Thomas A. Edison
