The magic word in your post is
interesting. Everyone has hard problems to solve, and most of the time those hard problems are borne of stupid decisions made 5 years ago by people who don't work there anymore.

I work on hard and challenging problems, which are by no means interesting, and I've often contemplating throwing myself out of a window just to experience some new shit :-)
If you have interesting work, let's talk, but you probably don't.
