“There's a way to do it better - find it.”

“Negative results are just what I want. They’re just as valuable to me as positive results. I can never find the thing that does the job best until I find the ones that don’t.”

“I find out what the world needs. Then I go ahead and try to invent it”

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

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

“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”

“If we all did the things we are really capable of doing, we would literally astound ourselves.”
