stopped thinking about better ways to solve a problem.
In his first job, when he was a teenager, Edison was taught how to use a telegraph. He
saw that it could be improved, so he was soon inventing new and better telegraph
machines. The perfect example of his approach is his most famous invention, the light
bulb. Edison tried more than a thousand different ways of getting electricity to make
light. He refused to stop trying until he found the material that worked.
As Edison liked to say, “Genius is one percent inspiration and ninety-nine percent
perspiration.” In other words, having a good idea is just the beginning: it’s the effort you
put behind that idea that gets the results.
