Marketing Your Jewelry

Sometimes I think marketing your jewelry or products is the hardest part of the job. Do you find that some days you spend most of your day trying to market your product? I go to my Amor De Plata Etsy site and spend time in the forums, bounce into Twitter and leave a few twits, go to Facebook and catch up. I haven't had time to log onto Myspace forever. I try to add friends on Scoutle and then go to my Artfire and check out forums. Do you have any special tips for marketing?
