Regardless of what kind of person you think Thomas Edison was there is one thing he can go down in history as, and that is he was persistent. Making the several hundred attempts at getting the light bulb working, or building all the components necessary to make DC viable for people, moving this many concepts forward was not easy for him, or the grad students that helped contribute to his many patents. With each of the ideas he worked on to develop it required a long period of time to get from the concept to the invention, but he recognized when he was onto something and would work persistently to get there. All one has to do is look through several of his famous quotes to get a sense of how he felt about giving up:
“Our greatest weakness lies in giving up. The most certain way to succeed is always to try just one more time.”
“I have not failed. I have 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”.
Thomas Edison was a man that was willing to try things multiple times until it worked, and he pushed others around him to do the same. Often you will fail the first time out of the gate getting traction with your concept, so it is important to be persistent and make adjustments each time until it works. Perhaps the initial concept you had was bad, and the idea is determined to be a failure. You are most likely still to stumble onto something great, so refine what you need and keep working on it till you strike gold.
