When I was just beginning to show and sell my paintings and photography, I ran across this quote by Alan Bamberger at http://artbusiness.com. I think there is a lot of wisdom in his words, and I often refer to it for inspiration:
"The passage of time is far more important than strategizing for success. Make art, get it out there, do what you have to do so that as many people see your art as possible, prove that you're a going concern, that you're in this for the duration, you're committed, you're not going to give up, and that nothing will stop you. Sooner or later, others will begin believing in you just like you believe in yourself, and that's when good things start happening."
Here's an excerpt from the about us page on his website: "Alan Bamberger, is an art consultant, advisor, author, and independent appraiser specializing in research, appraisal, and all business and market aspects of original works of art, artist manuscript materials, art-related documents, and art reference books. Alan's site is full of great information on the business of art, and anybody who is or is thinking about selling their art should read every word."
