I am writing full-time. I am NOT earning a full-time income from it. *Yet*. I am determined that that will happen.
But my definition of "full-time income" is mine, not everyone's. The last full-time job I had was as a teacher's aide, where I earned about $17,500 per year. So that's my goal for "full-time income" from my writing, at least to start with. In 2013, my earnings were about $4300. With a fricking ton of books out, but they're all from e-pubs and small presses, and some of those publishers do little to no promo or marketing, which puts it ALL on my shoulders. And that isn't good. I'm in the process of doing some major career renovations that I hope will bring me closer to my income goal.
I've been writing for publication since 2009, but 2013 was the year in which writing became my only career. Mainly because health issues have reached the point where I'm not able to hold down a "real" job anymore. However, because I'm designated as disabled, my health insurance and that of my children is covered through our state system. And I have a spouse who calls himself a "1950s guy in the wrong era"; he prefers being the one financially supporting the household, and recently took a second job to supplement the household income. But despite his self-proclaimed 1950s viewpoint, he does NOT expect me to do all the housework and child-related stuff, because he--even before I was completely able to do it--acknowledges writing as full-time work and a real career, and he'd rather have a messy house over having me not write because I have too much housework to do.
I'm kinda lucky...
