I suggest two steps.
First, ask yourself “what did I do right?” All too often we get caught up in the blame game. I blame others (employees, customers, the economy, the world) and most of all myself. This becomes a vicious cycle that doesn’t make things better. Celebrate success, even if it’s the smallest step.
Second, ask “What can I learn from this?” Every encounter can be a teachable moment. We can learn from the successful events, but we learn much better from the unsuccessful ones.
Lastly, put into practice what you learned. Feedback, unapplied is just noise. Knowledge applied leads to results.
