There may be as many reasons explaining what motivates a person to express themselves creatively as there are artists, but one of those reasons has to be the desire to, as Julia Margaret Cameron once recorded: "...arrest all beauty that came before me."
Recently came across some excerpts from the writings of Viktor Frankl that perhaps explains that desire more fully:
...it is not only the uniqueness of an individual life as a whole that gives it importance, it is also the uniqueness of every day, every hour, every moment that represents something that loads our existence with the weight of a terrible and yet so beautiful responsibility! ... [W]hat we achieve by seizing the moment is, once and for all, rescued into reality... In truth, it has actually been preserved, in the sense of being kept safe....the reality that we have rescued into the past in this way, can no longer be harmed by transitoriness.
