Melissa Plaut left a corporate advertising job to become a New York City cab driver ... and wrote all about her experience in her blog (and now a book):
She has suffered neck spasms, kidney pains and eye twitches from driving 12-hour shifts. She has scraped dirt from beneath her fingernails from handling so many dollar bills.
"After each shift I would come home and type," she says. "I would vent and complain and curse. I would bitch about traffic. I would bitch about cops."
Her friends had gone off to work high-profile jobs they loved. Her parents were embarrassed to tell friends their daughter drove a cab.
"I'm thirty years old. I live alone with two cats. And I'm a cab driver," Plaut writes in her book.
The job has taken its toll, but not everything about it depresses her. Along the way, she has learned a lot about people, the world and herself.
