Don’t sell mediocre work just because you can. A quick peek through etsy will show you that there are plenty of people producing unexceptional art/jewelry/pottery – and selling it. Don’t add to that pile, it is not the path to distinguishing yourself. If you need to make a quick buck go deliver papers or something. Sell some plasma. But don’t put your name on something that is mass produced and soulless. Brutally assess your work. Find other people whose opinions you trust to help assess your work. If you need to be treated with kid gloves then consider another career. Part of being an artist is dealing with criticism. Make something special that shows who you are and hone that talent before putting yourself in the marketplace. Give it your all.
