…pay attention to what you envy. Jealousy is an ugly emotion, but it tells the truth. You mostly envy those who have what you desire. I met my own envy after some of my former law school classmates got together and compared notes on alumni career tracks. They spoke with admiration and, yes, jealousy, of a classmate who argued regularly before the Supreme Court. At first I felt critical. More power to that classmate! I thought, congratulating myself on my magnanimity. Then I realized that my largesse came cheap, because I didn’t aspire to argue a case before the Supreme Court, or to any of the other accolades of lawyering. When I asked myself whom I did envy, the answer came back instantly. My college classmates who’d grown up to be writers or psychologists. Today I’m pursuing my own version of both those roles.
