Can we just kick this over to Mark Kostabi?
@bassknives Then she can go be an artist, too!
If you want to quit your job to become a visual artist, you really should read Why are artists poor? The exceptional economy of the visual arts by Hans Abbing. He quit his job as an economist to become an artist, and he is actually successful as an artist (in that he has gallery representation), so the man knows whereof he speaks.
Also, I had a job where I telephoned alumni of the art college where I am a student/sucker, and out of the hundreds of people I spoke to, only one person was supporting himself as an artist, as opposed to teaching, curating, working in a bar or customer service job while making art on the side, working in a bar or customer service job without making art on the side (most common), or basically living on the dole (also common). The people I spoke to who were happiest were ones who had managed to find a way to keep their spark of creativity alive through what you might consider a faux-creative career, such as landscape garden design.
Forgetting the money for a moment...If you are really an artist, you will already be consumed by your artistic practice in your spare time. If you aren't doing that now, it's time to find ways to be happy in something more steady and renumerative. It's amazing how hard to be creative it is when you are completely broke and sick of yourself.
