I must confess to my readers that part of my motivation for writing is so that eventually I can get a paid gig, just one paid gig, so that I can answer this question, “Stay-At-Home-Mom AND Freelance Writer” instead of just “Stay-at-Home-Mom”.
Why can’t you be a freelance writer* now?
I called myself a programmer before I actually got a job with a title that had “Programmer” in it, because I wrote good, functional, commercial-quality software, dammit! I was just making it available online (which, back then, was CompuServe) or helping out a friend with a software/hardware business who “paid” me in discount hardware (and with a sincere and persuasive reference for a job that I applied for, which the HR person said was what won her over to recommending me).
*who just hasn’t, actually, quite so much gotten paid in a literal sense… yet
