In addition, I do not want to sacrifice my marriage for a JD.
I would put it more strongly: I will not sacrifice my marriage for a JD! Or for my career after law school, for that matter. My husband wants me to do well -- he sees this as a family choice. So he understands that I won't be able to spend as much time with the family as I otherwise would. But knowing that ahead of time, we're committed to spending as much time together as possible, and making that quality time. That commitment is then my driver for staying focused during the day.
