Quote by George Stephenson

"A man who does things wrong will learn the consequences; a man who does nothing will learn nothing."

"The greatest obstacle to progress is the fear of change."

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

"Success is not final, failure is not fatal; it is the courage to continue that counts."

"Imagination is more powerful than knowledge."

"The world is full of wonders if you know where to look."

"You have the imagination of a child, Lucy"

"The world is full of mysteries waiting to be solved."
