Thomas A. Edison

“I have not failed. I've just found 10,000 ways that won't work.”

“Genius is one percent inspiration, ninety-nine percent perspiration.”

“There is no substitute for hard work.”

“Waste is worse than loss. The time is coming when every person who lays claim to ability will keep the question of waste before him constantly. The scope of thrift is limitless.”

“Many of life's failures are people who did not realize how close they were to success when they gave up.”

“Our greatest weakness lies in giving up. The most certain way to succeed is always to try just one more time.”
