Oh wow; I really like this questions, it makes me think. (:

A lot of things inspire me to write; mostly music. If I didn't have music I wouldn't even write.
Also when some of my favorite authors update their stories; it always makes me happy; when I'm happy also I will usually write, or if I need to calm down or I'm stressed out I usually will grab a notebook or get my laptop and start writing; if it's raining to, I always like to write when it's raining.

Even people saying something can inspire a story for me to write.
