What works for me is a lot of little things. My B&M choices are quit work for a public U, full time day program or keep working and attend a private evening program. When I think about no salary or paying about $40K per year for tuition, these do not seem to be a real choice. So, "correspondence" seemed to be the answer, especially given the way in which I expect to use a legal education.
First, this part time correspondence program is as full time as it gets. I'm putting in 30 to 40 hours per week. So, at the top of my list is that I have a very understanding wife and no kids. I only do the essential things around the house. I moved into a work assignment that has only minimal travel and I'm staying in a area of responsibility where I have strong skills. I did some work to increase my reading speed and would like to bump my speed to be faster still. I work from a home office; no commute means more study or sleep time.
Make sure you know yourself: know that you're motivated, or driven, enough to stay with the program for four years. And, know how you learn so that you focus your time on the most effective study approach. If you decide to buy study aids, buy those study aids that compliment your learning style.
