Edison was famous for bragging that he only needed 2-3 hours sleep a night. Then when Tesla came to work with him he once remarked to a reporter "Yes, he only sleeps 2-3 hours a night but he naps for 5-6 hours during the day."

Edison Vs Tesla debates often end up going no where, this is because the debates take the nature of debate between two school of thoughts. One which believes that learning the body of knowledge and using proper academic approach to research is the right way to success(Tesla), other approach is to take a interesting problem without having no background and prior knowledge of what you are going into, but as you go deeper you begin learn and do things by experimenting on the way(Edison).

Edison approach takes time, a lot of work and thereby you need to find ways of being more productive. Both methods have their plus'es and minus'es.

But.. If you find some body very hardworking, going over the counter to put effort in his work to achieve something and he ends up being more successfully than everybody else. That shouldn't look surprising. And that precisely what happened with Edison and Tesla.

Although Edison lost the war of currents, but comparing their lives as a whole Edison ended up achieving far more than Tesla.
