What is art?

What is art? What classifies it as art? I believe art is everything and most importantly personal. I think that the beginning of objects like the blue prints are imagined by one's mind and therefore are their own art. Once it is mass produced i think it is just humans' way of making money. Art is what one person produces through a personal idea or can be anything that moves one's feelings. You can decide what beauty is through the way it moves you or if it inspires you to take action in any way. I think art can have function because the urn has a function but we see it as such a beauty from the people of our past and are able to study them so much more through this kind of art. I may not react to all kinds of art or even like it, but i do believe an idea that is constructed and presented is art.
