I post a lot on this website and I know I do.  The inspiration well runs dry for me sometimes, and I'm just wondering (fellow writers), that when you get inspiration, where does it come from?

Generally, when do you get inspired the most?  Where do you get the most ideas?  Anything pertaining to inspiration can be discussed here.

Personally, I get the most inspiration when I'm trying to sleep, taking a shower, or watching the rain fall.  What about you?
