In this perfect world, there are certain imperfections that catch your eye. That's what works for me. I don't concentrate on being perfect, but instead put that effort behind my craft and being true to myself. I don't conform to pressures outside of me. I am confident about myself.
I believe that I improve with every craft I make - most craftsman will probably tell you the same thing. I'm still learning my craft and will be until the day I drop dead at my desk. In my opinion, art isn't something that can be perfected. There's always room for improvement.
