Other people can see the back of your head. Let them tell you when there’s gum in your hair.

Self-knowledge has a limit built into it. Your view comes from inside, which means whole parts of how you come across are simply unavailable to you while being obvious to anyone standing nearby. Refusing outside information keeps you comfortable and slightly out of date. The people close to you are usually waiting to be asked rather than looking to criticize.

Ask one person what you are like to be around when you are stressed. Let them answer without defending yourself halfway through. Thank them, and make it safe enough that they would say it again.
