For Joan the idea of doing something where "you're your own boss" is everything. She's finally in a place that the work she does won't get discarded by a man who didn't appreciate what she's done (like Jaguar or how she was treated upon coming to McCann.)

Peggy doesn't have a problem with that at McCann. She can handle herself fine, and as her agent or whatever told her, you can do a few years at McCann and then do anything you want. She's already in control of her destiny.
