"Negative results are just what I want...." - Quote by Thomas Edison

“It is the best book ever written on the subject. There is nothing like it!”

“If I had not had so much ambition and not tried to do so many things, I probably would have been happier, but less useful.”

“A good intention, with a bad approach, often leads to a poor result.”

“Each time you fail, you have eliminated another wrong option.”

“Success is as dangerous as failure. Hope is as hollow as fear.”

“Failure comes from ego, greed, envy, fear, imitation. I have success not because I am smart, but because I am rational.”

“Through error you come to the truth! I am a man because I err! You never reach any truth without making fourteen mistakes and very likely a hundred and fourteen.”

“The learned man knows that he is ignorant.”

“I have discovered photography. Now I can kill myself. I have nothing else to learn.”
