And I don't mean like "because I was good at it when I was small" or something. Just tell me the reason for which you compose, your motive... I personally compose because I think music is a form of expression that no other art can provide you with. Plus, it is something moving, not constant (like statues or paintings) and can change through time (revised versions, imagine DaVinci revising the Mona Lisa after 10 years), plus it is something you can do for entertainment, both for you and others.
