Perfection

I often times have difficulty feeling satisfied with my art whether it be drawing, ceramics, painting or photography.  I always feel like it's not good enough, never fulfilled or if I am it's only for a short time.  It makes me feel sort of depressed sometimes because I definitely feel that my ability at art, sort of what I'm best at, reflects who I am, it's my identity.  I feel this way even though my friends and family both enjoy what I do.  That leads me to a new subject.  Does one practice art for themselves or for others.  I can only speak for myself but I'm not sure I would have as much drive to do it if I knew that people weren't going to appreciate it afterwards.  I suppose that for me it's a source of expression but would we feel a need to express ourselves if there were no one to express our feelings to?  I would guess not.  I feel like there are a lot of artists that I look up to that seem to put on a facade of doing art exclusively for themselves.  Maybe I'm wrong, maybe it's not a facade, maybe I'm just not in that place in my life where I can feel completely comfortable making art for myself, without the judgment from people on the outside.  As humans we are so social that I cannot think that there are any artists that would not be effected in some way by their social group.  It's a difficult question to answer.
