Where do you get your ideas?

It turns out that most of my work ideas come while getting ready for the day. Usually while taking a shower. I am not sure why this is. Maybe my brain has been crunching all night and finially the rest of my body wakes up enough to evaluate what has been going on all night long?

Here is a great list of where ideas do and don't come. An interesting project is to go through this list and find out how much time you spend in areas where ideas come from and from where ideas don't come from.
