To be an artist and put your art out there at the mercy of public opinion requires faith. I'm not talking about religious faith. I'm talking about a certainty, trust and confidence in your art. When you are faithful to your vision and hold strong in your creative belief system then you can become somewhat more impervious to the negative comments and unsupportive opinions of others. It doesn't matter what they think or say. But it really, REALLY does matter what you think and say about your art - what are your convictions as an artist? What do you really believe to be true about your work? You no longer need to convince anyone when you believe strongly in your work, your style, your ideas. Look for your own weak spots and bolster them with a little faith.
