I was the envy of my 30-something friends in Palo Alto, Calif. I had my own law office right on California Avenue. People charged with crimes handed me cash, in advance, over a big oak desk. Occasionally, I’d make a couple of grand in an afternoon. But soon, my body started giving out one part at a time. First a shoulder, then my lower back, knee cartilage, neck vertebrae… After 10 years as a law student and lawyer, working in a profession I didn’t like was taking its toll.
