My favourite quotes by Thomas Edison

“Many of life’s failures are people who did not realize how close they were to success when they gave up.” 

“Opportunity is missed by most people because it is dressed in overalls and looks like work.” 

“Being busy does not always mean real work. The object of all work is production or accomplishment and to either of these ends there must be forethought, system, planning, intelligence, and honest purpose, as well as perspiration. Seeming to do is not doing.”

“I have not failed. I’ve just found 10,000 ways that won’t work.”
