In figuring out how to function as a female lawyer in a male-dominated profession, some women opt for the part-time, limited-hours approach. They want a career in law, but not one that consumes or defines them. They want time with the kids and time for themselves. These are the women who happily (or begrudgingly) march along the mommy track.

And then there’s Mercedes Meyer. She belongs in the camp of the women who jump in with both feet. They accept the long hours. They agree that rainmaking is part of the job. They’re willing to play by the men’s rules. They’re ready, in short, to do what they need to do to crack that glass ceiling without necessarily redesigning the architecture of the entire building.
