I read an article on Medium last week with the title listed above. I thought it was worth sharing because it offers a balanced, sensible solution to the age-old dilemma of doing what you love versus doing what will pay the bills. It suggests doing what you love as a side gig while having a good-paying job to support the side gig. I think this is especially important if you have a spouse and/or dependents. If you haven't read this article yet, feel free to go over there and read it before commenting. If you did read it already, what do you think?
Edited to Add: One point I don't the author addressed very well is time management. Even if you "only" work a 40-hour week (technically, my job is 37.5 hours a week), there's still commuting, daily tasks, and other responsibilities that take up your free time. If you have dependents, it can be very difficult finding time for yourself, let alone a side gig. That's why I write on lunch break, during my son's tae-kwon-do class, and any time I can steal for it.
