“Many times what we perceive as an error or failure is actually a gift. And eventually we find that lessons learned from that discouraging experience prove to be of great worth.”

“Some of the best lessons we ever learn, we learn from our mistakes and failures. The error of the past is the success and wisdom of the future.”

“Don't be discouraged by a failure. It can be a positive experience. Failure is, in a sense, the highway to success, inasmuch as every discovery of what is false leads us to seek earnestly after what is true, and every fresh experience points out some form of error which we shall afterwards carefully avoid.”

“Some of the best lessons we ever learn are learned from past mistakes. The error of the past is the wisdom and success of the future.”

“Although failure is a great teacher, we cannot afford the time to learn from our failures. Human societies cannot be subjected to such a process.”

“We should not look back unless it is to derive useful lessons from past errors, and for the purpose of profiting by dearly bought experience. ”
