A commonly stupid question asked by intelligent people is "what is art?". I came to the conclusion art is something that only exists for the fuck of it. That simple. It's only as sophisticated and articulate as you wish it to be. Standards, objectivity and rules are relative to personal arbitrarily requirements to be appropriate to our own expectations. Having good taste, does not earn a special insight to what art is. Only what is expected of it to be taken seriously.
Self expression, creativity, narrative, social relevance and emotional output etc. are only a context. Don't let the expectations of context confuse you. Art isn't that complicated.
