it's pretty obvious there is a pattern to everything created. It's interesting how each artist has some sort of a signature. it's actually pretty unavoidable. I think i just don't like the idea of making the same things over and over again. i think i feel that way about life in general. i think we have the potential to go after life & experience everything fully. but so often we get comfortable w/ the things we know & do things the same all the time.
I feel one major challenge as an artist is to keep moving forward. Recreating what you know how to do already doesn't necessarily allow much room to grow. I think you can avoid staying in the same place creatively by learning more about the things around you. If you take in more information & allow things to influence the way you see things, you will start to create things that reflect that.
I recently read something Duchamp said, "I have forced myself to contradict myself in order to avoid conforming to my own taste." In a way i think challenging your own ideas at some point can do some really great things for your perception & creativity. Not only will you see a different perspective of your work, but maybe it will give you new ideas to build on.
