How do you find motivation?

I'd seriously like to know: How do you find the motivation? To write and post stories that is. I love my story, and although I don't think I'm the best at writing, I still enjoy doing it. However, lately I haven't really felt motivated to write or post anything. I have like 2 chapter made for my story, I just don't want to post them. So.. Can people please comment and tell me where you get the motivation from? Much appreciated ^_^

And now I got to write something random 'cuz I guess my little paragraph above this one is only 80 words long. Stupid Mibba telling me I need 20 more words. Oh well, hope this will be enough now. Yupp <3
