Missing a deadline can happen to the best of us. You can rebuild trust with others if you miss a deadline with grace.
Here are the simple steps to take when you blow a commitment:
1. Notify others the second you realize you will (or may) miss the deadline.
2. Apologize profusely and with genuine remorse.
3. Make no excuses or explanations. None. Not one peep.
4. Commit to a realistic new deadline.
5. Meet it (or beat it).
6. Conduct a post-morten to figure out what you did to make yourself late.
7. Rebuild trust by learning from the error.
