Art can be anything, but not everything is art: for art is creative, emotional, made, poetic, visual, and it is even inspiring. Art is not just what others tell you, but what 'you' want it to be!
Anyone can create art, though not all can have the same skill level in certain mediums as others do: for artists are always improving, changing, & for lack of a better word, evolving. Therefore, all are unique in one sense or another, even when similar. So whether you spread your wings & take flight, fall to the depths below, or end up somewhere in between: art becomes what you want it to be, for it is an extension of one's self.
