My Mother Was The Making Of Me.

Show Me A Thoroughly Satisfied Man - And I Will Show You A Failure.

I Did Not Fail Two Thousand Times. I Merely Found Two Thousand Ways Not To Make A Lightbulb.

Of The 200 Light Bulbs That Didn't Work, Every Failure Told Me Something That I Was Able To Incorporate Into The Next Attempt.

If There Is A Better Solution... Find It.

To Have A Great Idea, Have A Lot Of Them.
