So you’re self-employed. Congratulations! Now you can go to the gym at 3:30 p.m., when no one’s there. Braise a pork shoulder on Tuesday afternoon and actually make it to your kid’s performance of “Third Graders Sing the Lady Gaga Songbook.” (You can also nap. Not that you'd ever do that.) As long as you can fight off the specter of loneliness by talking to the cat all day, there are many benefits to the gig economy.
