Businesses run on products: product conception, product development, product sales, product redevelopment, and so on. Products products products. If we are not buying a product then we are producing a product or selling a product or discarding a product in order to replace it eventually with another theoretically superior product. These products are largely made for two reasons: to make money for the creator/sales person and to satisfy a utilitarian need that some aspect of our human existence has necessitated. Sometimes that aspect is basic: a shirt to protect us from the cold, shoes to protect our feet, etc. Other times - and this is often the case - the need goes much deeper - products are bought and sold to satisfy a desire to be attractive, to be beautiful, a desire to reflect some part of our perceived identity, and, most importantly, a desire to be loved. In the end, it seems difficult to decipher the difference between 'basic need' and 'desire'.
Artwork, at its purist, at its most whole, is born from the desire - an inner urge - to create. It is the desire of self-expression and bringing something new into the world. That urge drives us forwards - compelling us to always do more - because that which we have already made is never fully satisfying.
