Don’t take it personally
The phrase, “Don’t take it personally” is worse than useless.
What can you say instead?
Remember the CPD formula for making requests?
Make it clear (ask for a start or stop behavior), positive (ask for what you do want, rather than what you don’t), and doable (by the other person).
Wanting someone to not take something is a perfectly reasonable request, but is it doable?
How about saying: “The next time you receive criticism, can you reflect back on what you heard before reacting?”
OK, that’s doable.
