Enjoyment Factor.
What is it about computing that you enjoy the most?
Could it be some of these or something else: the learning of something new, the marriage between visuals and music, composing ambient tones, being fancy with pixels, or simply the love of creating magical effects & wizadry?
Personally - I generally get a buzz from trying and being creative with graphics and code. I'm not really all that with the music side of things. But I do enjoy putting together stuff, granted some things don't turn out as expected which can be quite cool ( often not, hehe ); and also there's the worry of running out of effects to do, when that happens I tend to wait for inspiration to spring. And it's a nice bonus if someone else likes them too.
Thanks,
Clyde.
