We perform different selves for different people. Your coworkers see one side of you. Your friends another. Your lovers still another. You’re all of these, and none of these — all at the same time.
You can understand yourself in lots of ways. Your job does say something about you. So do your habits. And your likes and dislikes. Your fashion sense. The way you talk. You’re the sum of all that, plus what different people think about you.
Don’t waste your life trying to construct the full picture.
