I like art because I feel it's something positive. When I create quality* artwork, I feel I'm contributing something of value to society. Quality artwork can be enjoyed by many people like a concert/ . Real artwork is one the most positive aspects of our species.
It's a nice counter balance to all the horrors in the world.

There is some "art" I dislike. Like when people put fish in blenders or tie a starving dog to a wall. This in my mind IS NOT ART!!!...Except since some people call it as such, I include it.

* I seriously hope what I'm working towards IS quality. I don't feel low quality or hobbyist quality artwork has the same impact.
