Quote by Thomas A. Edison (1847-1931)

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

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

• Our greatest weakness lies in giving up. The most certain way to succeed is always to try just one more time.

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

• To invent, you need a good imagination and a pile of junk.

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