Quote by Thomas Edison (1847-1931)

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

• There is no substitute for hard work.

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

• There is no expedient to which a man will not go to avoid the labor of thinking.

• There is time for everything.

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