Making an honest mistake is acceptable. Failing to fix it is not.
Money has a fixed value. People can have unlimited value.
What you did in the past is how you got to today. What you do today is how you will get to the future.
Be the exception to the rule. It's the surest way to become exceptional.
You can't find what doesn't exist, but you can create it.
What matters more? What you said you'd do, what you hoped to do, or what you did?
