If you know exactly who you are, nobody’s opinion can rearrange the furniture.

Opinions land hardest wherever you are unsure. A comment about something you have already settled bounces off, while the same tone aimed at a thing you privately doubt rearranges everything for a week. The strength of the reaction is not really about the person talking. It maps where your own footing is thin.

The next time something somebody said sticks to you for hours, ask what it hit rather than how unfair it was. Write down what you actually think about that subject. Settling the question yourself is what stops the next comment from getting in.
