“Failure is just another way to learn how to do something right.”

“There is no better insurance than the knowledge of how to do something the right way. There is no greater peace of mind than knowing you did it the right way.”

“First, not a word more from you about the past. There was an error in your calculations. I know what that is. It affects the whole machine, and failure is the consequence. You will profit by the failure, and will avoid it another time. I have done a similar thing myself, in construction, often. Every failure teaches a man something, if he will learn; and you are too sensible a man not to learn from this failure.”

“In a way, “failure” is just another word for “the journey,” for not being there yet but on the way. It’s the road we walk on to get wherever it is we’re trying to go.”

“ Yes,I'm afraid you're right. Trial and error isn't a bad way to learn how to build an aircraft,but it can be a disastrous way to learn how to build a civilization.”

“We learn to do something by doing it.There is no other way.”
