La sabiduría de Thomas Edison (1)

• "Genius is one per cent inspiration, ninety-nine per cent perspiration."

• "Faith, as well intentioned as it may be, must be built on facts, not fiction--faith in fiction is a damnable false hope."

• "I never did a day's work in my life. It was all fun."

• "Just because something doesn't do what you planned it to do doesn't mean it's useless."

• "Many of life's failures are people who did not realize how close they were to success when they gave up."
