I have not failed. I've just found 10,000 ways that won't work.Many of life's failures are people who did not realize how close they were to success when they gave up.There's a way to do it better, find it.The three great essentials to achieve anything worthwhile are, first, hard work; second, stick-to-itiveness; third, common sense.To invent, you need a good imagination and a pile of junk.Genius is one percent inspiration, ninety-nine percent perspiration.Our greatest weakness lies in giving up. The most certain way to succeed is always to try just one more time.I never did anything worth doing by accident, nor did any of my inventions come by accident; they came by work.I never did a day's work in my life, it was all fun.We often miss opportunity because it's dressed in overalls and looks like work.Vision without execution is just hallucination.Thomas Edison1847 - 1931
