Where do you get your ideas?

I really don’t know where I get my story ideas. The books tend to start in different ways. Sometimes it starts with a cool title (How To Marry A Marquis) and sometimes with an opening sentence (To Catch An Heiress). Other times I have a character before I have a book idea (Simon in the The Duke And I.) To be honest, I don’t really care where I get my ideas–as long as they keep coming!
