“Everyone makes mistakes, the important thing is what we learn from them. Don’t waste time beating yourself up over the mistake, just learn from it and move on.”
My first area manager probably didn’t coin this phrase, but he was an excellent mentor for the brief period we worked together. I give him credit for first introducing it to me.
Wisdom, both professional and personal is the result of experience. Experience is the result of taking consistent action, of moving forward and executing. Mistakes are simply a type of result of that execution. So wisdom comes not from the mistake but what is learned from it. Failure is merely a perspective, an attitude that a person chooses to accept or reject.
