I Never Quit Until I Get What I Want.

I Speak Without Exaggeration When I Say That I Have Constructed 3,000 Different Theories In Connection With The Electric Light, Each One Of Them Reasonable And Apparently Likely To Be True. Yet Only In Two Cases Did My Experiments Prove The Truth Of My Theory. My Chief Difficulty Was In Constructing The Carbon Filament... Every Quarter Of The Globe Was Ransacked By My Agents, And All Sorts Of The Queerest Materials Used, Until Finally The Shred Of Bamboo, Now Utilized By Us, Was Settled Upon.

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

The World Owes Nothing To Any Man, But Every Man Owes Something To The World.
