Over at the HBR Blog Network, Dan Pallotta has published an anguished story about the failure of his business 10 years ago. The tone of regret, sadness and bitterness illustrates why failures can be so devastating. Even the lessons learned (example: "I have a less sophomoric approach to trust. Don't offer it freely, unless you're prepared for the consequences") reflect a deep and lingering pain.
Living with The Mistake Bank for five years now has taught me that letting go of anger and bitterness can greatly help to learn from failures and move forward positively. However, it's good to have a reminder that failures leave a deep imprint, and are difficult to separate from personal feelings of injury and injustice, even 10 years on.
