Art is a compulsion.
It's an expression of joy that is not limited by social acceptance or academic labels. I create without regard to what is "acceptable" in a certain medium and focus instead on what each piece requires to reach completion. The journey and the process of creating is often as much a part of the finished work as the end result.
I've always seen art as being a byproduct of an artist that, like any creation, must be fed and fueled as it develops. This outlook has been useful in helping me grow as I develop my range of abilities. Experimenting in as many techniques as possible and exploring the strengths of each medium is a good way to add another tool to my "bag of tricks" that may come in handy when executing a particular artistic vision.
