I believe I’ve mentioned before that we are all only human. We make mistakes. Would that it weren’t so, but. . . there you are. So, what do you do when you make that mistake at work, and get “called on the carpet,” so to speak?
You own it. You make it right. You forgive yourself (this one is important! Don’t keep beating yourself up over it.) And you move on. That probably includes making sure that you won’t make that same mistake again. But, I’m sorry to have to tell you, you’ll probably make a different one. Don’t despair, because, you know, you’re only human (see above).
Thanks to Letters to a Young Librarian for reminding me of this, so I can, in turn, remind you.
