This is one of my favorite quotes, because first off I in 4th grade we had to choose a famous person and do a project on him/her (he had to have passed away or else you couldn't use that guy) and I can't describe how hard I worked on it and now I know a lot about Edison and this quote. Second this was one of my favorite of his quotes and its like saying even if you fail keep trying. This quote also reminds me of another quote from soccer player (ronaldinho) and it's "don't keep practicing until you get it right, practice until you can't get it wrong.
