All leaders make regrettable decisions; as a matter of fact, if you haven't made any bad decisions, you are not taking enough risk or learning enough to continue growing as a leader.
Everyone makes mistakes; no one is perfect, but how you handle the aftermath of that mistake is the key. Great leaders ensure that poor choices don't compound their mistakes. They also make sure they learn from their mistakes and develop actions to handle the situation differently in the future.
I concur. Having made just about every mistakes in business, I don't see this as bad. Just part of moving forward.
