"Art" cannot be clearly defined because what one person considers "Art", another doesn't.

"Art" is subjective.

"Art" comes in all shapes, colours  and sizes.

"Art" comes in a multitude of themes and genres.

"Art" can be man-made or made by nature.

"Art" is in the eye of the beholder.

"Art" can be in such a form that it can be appreciated by 1 or all of the 5 senses.

"Art" can be healing or hurtful. It can be soothing or stress inducing. Basically "Art" creates emotion, even if not readily noticed.

"Art" can be found anywhere and everywhere.

A true "Art Enthusiast" will have a broad mind when it comes to art and even if it's not to their "taste" recognize it as an expression of creativity, and not compartmentalize it into narrow catagories.

"It is good to see ourselves as others see us. Try as we may, we are never
able to know ourselves fully as we are, especially the evil side of us.
This we can do only if we are not angry with our critics but will take in good
heart whatever they might have to say." - Ghandi
