I have put over 80 creative writing exercises up on my website.  Just when I think I can't come up with something new, I do.  That makes me very inspired.
Recently I've been editing my novel that I finished before Christmas.  I was reading it and it was like someone else's book.  I laughed.  I cried.  And when I was through I was inspired to write.  Well, if I feel that way about my own book, I'm sure someone else will too.
Someone once asked me why I write?  I told them because I breathe.
