Sticking To It Is The Genius.

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

Most Of My Ideas Belonged To Other People Who Never Bothered To Develop Them.

Results? Why, Man, I Have Gotten Lots Of Results! If I Find 10,000 Ways Something Won't Work, I Haven't Failed. I Am Not Discouraged, Because Every Wrong Attempt Discarded Is Often A Step Forward.

A Failure Teaches You That Something Can't Be Done-that Way.

Consider Data Without Prejudice.
