If one bad comment can wipe out a hundred good ones, you’re outsourcing your mirror.

Negative comments weigh more than positive ones for almost everybody, so this is not a flaw particular to you. The difficulty is that it hands one stranger the power to set how you see yourself for a day, and they did not earn that. Your sense of who you are has to come from somewhere steadier than the last thing typed under a post. The hundred kind ones were not less true.

When one lands, notice how much of your afternoon it is taking. Ask whether you would take advice from that person about anything else. Then go somewhere the feedback comes from people who actually know you.
