No, it's not all about creativity and inspiration and expressing yourself. In fact, as an artist you're a small business owner. Besides bookkeeping you have to expand your network, find new customers, stay in touch with the gallery world, keep your website up to date, produce and post new videos, write a blog, take care of crating and shipping, send invoices, fill out customs declarations and oh yes, produce paintings.
On top of that (like every small business owner) you have to deal with an unsteady income and that requires a specific mindset. You got to be realistic, but at the same time not worry to much. You got to use all available resources and yet accept there are circumstances (like an economic crisis) that you can't do a thing about.
I had a steady job for quite some time as a high school art teacher. It was nice to get a paycheck every month. I liked teaching, but still I prefer being my own man, making my own stupid mistakes, rather than trying to make the best of somebody else's stupid mistakes.
So I count my blessings. Just finished a small 15 x 45 cm painting of a figure on the beach. Planning on a number of oil sketches on paper. Being a painter is cool. I'll keep you posted.
