Despite, or perhaps because of, its interference with the attainment of structural unity, I think the preliminary fiction should not be revised smaller, thought it is not the subject of the essay even in the present draft. It's an auxiliary illumination in at least two senses, and should remain as it is.

In the decision-tree of thinking about the future of your practice, you have taken the first major step, which is to choose Why your practice will be whatever it turns out at any given moment that it is. Now you need an academic program that helps you to know How to construct such a practice for yourself, including both What you will need to know how to do, and With Whom you need to have professional connections in order to do what you want. One way is to take a salary from a law firm and do what and with whom it directs. (Remember, in relation to one of your proposals, that such a practice will insist on its right to approve, actually to choose, what pro bono matters you can work on.) Another way is to run your own practice. These also are not exclusive choices and law school should be able to train you for both. Surfacing what interests you as potential subjects of practice is always valuable.
