Thomas Edison was another failure. Only lasted three months of official schooling due to his wandering mind, and his teacher felt he was “addled”. His mother then took over his education and taught him at home. He then developed hearing problems at an early age.

This addled young man grew up to have 1,093 patents in his name as well as creating the phonograph, motion picture camera, and a practical light bulb.
When asked about failing at making the light bulb so many times before success, “I have not failed. I’ve just found 10,000 ways that won’t work.”.
