It’s called “freelancing.” It actually comes from mercenary terms. Those fighters who did not serve any particular lord were “freelances.” They would sell their skills to the highest bidder.
Since the pen is mightier than the sword, it is now up to the poor and starving artists to sell their swords. Pens. Whatever.
I love freelancing. Nothing is better than that feeling of landing a gig and knowing you’ll have one paycheck, at least. Unfortunately, at least in the beginning, almost all of your work is spent looking for work. So you get to spend hours not getting paid… looking for a way to get paid.
My steady gig I’ve been doing for the last couple months finished yesterday, so I’m back on the hunt. If you can put me on a scent, I certainly wouldn’t complain.
