Don't quit

I'm working on a project and the client has been extremely -- EXTREMELY -- difficult.  She has been so infuriating that I've thought, many times, of quitting.  However, this is a short term project and I've been creating games to get me to the finish line.  If it were a long-term project, I'd work to get out of it.  But not on this one. My reputation keeps me from quitting but it stays on my mind.  But,  I would take a bigger hit so I keep saying "Don't quit."  But, I've advised my friends/associates to take me out on Michigan Avenue for a beat down if I ever work with her again.  So there!
