While writing is my passion it's also my job. Most of the time, I don't have the luxury of laying around waiting for my muse to inspire me. It helps that I have new ideas for stories every day. Fear of not getting to write them all keeps me writing. So does the fact that when I don't write I get out of sorts and grumpy. But the real answer to your question is that everything inspires me to write because I am wired to be inspired to write.
