It is devastatingly human to make mistakes.
I am human, therefore _____.
What should I do when I make a mistake?
Learn what I can. Try not to do the same thing again. Explain why it happened. Make amends where I can. Apologize sincerely, without making it about me. Recognize that another person’s response to that apology is not up to me. And then let it go and move on, because this is all I can do, and ruminating over the past won’t help anybody.
