Self-employment and entrepreneurship are sometimes sold as the ideal way to work. The truth is that people can find work happiness, satisfaction and meaning in regular jobs too.
I used to work with a freelance stage manager at a theatre. My memory of her was seeing her dash around the theatre, run from site-to-site, and she always seemed to be rushing. I ran into her a few weeks ago and she was calm. I said something like, "you seem a lot more content now, what changed?" and she said, "I got a day-job. I make a decent and steady income, I have evenings to myself, I go to the theatre for the joy of it, and I'm happier."
That's what day jobs can do for people.
