"Restlessness is discontent and discontent is the..." - Quote by Thomas Edison

“The memory of my mother will always be a blessing to me.”

“I try not to invent things that people don't need.”

“I never pick up an item without thinking of how I might improve it. I never perfected an invention that I did not think about in terms of the service it might give others. I want to save and advance human life, not destroy it. I am proud of the fact that I never invented weapons to kill. The dove is my emblem.”

“The innovator has for enemies all who have done well under the old, and lukewarm defenders in those who may do well under the new.”

“Little by little, one travels far”

“Isn't it absolutely essential to keep a fierce Left and fierce Right, both on their toes and each terrified of the other? That's how we get things done.”

“There is no greater disaster than discontent.”

“This world, such as it is, is not tolerable. Therefore I need the moon, or happiness, or immortality, I need something which is perhaps demented, but which is not of this world.”

“Discontent is the seed of ethics.”
