In the same context, I define side-gig as something one does to earn extra money in addition to a job. Hopefully, it's something you enjoy doing, but it doesn't have to be. The goal includes income. Maybe it's cash to make ends meet, or maybe it's to buy the extra things you want. Either way, the intent is to create a model that turns a profit. However, you're not looking to quit your day job. A side-gig is not an exit strategy. You're a side-gigger and you know it.
