I agree with the general message of what Watts says.
To be honest, I'd probably still do something that would give income in order to support two of my other loves that require it. However, my job wouldn't be a job to me.
I love picture framing. Preservation of art. I used to be a framer and I've framed pieces and preserved them for private collections and galleries. Some of my stuff has even been put into museums (small ones). I've had the honor of framing 3 original Dali pen and ink drawings. I've shadow boxed a carving carved by a master carver from Africa that to my last knowledge was part of a private exhibit on African carvers and their culture.
To me... -shakes hir head- That isn't a job. Framing to me is a love, a passion. It started out as a job, yes. But the more I got into it, the more I began to appreciate it. Everyone cherishes items. There's meaning behind everything and for someone to spend $200 to frame their child's "useless scribbles," shows that they care enough about those scribbles to have them preserved.
No art is meaningless. No matter how useless, ugly or decrepit it might be. It doesn't have to be a Dali, a Warhol, or a Rembrandt. It doesn't have to be an Ansel Adams, a Paul Strand, or an Alfred Stieglitz. It can be anything from you or me.
So what would I do? I'd be right back being a framer... and hopefully if things work out, that's exactly what may happen.
