One of the biggest misconceptions I had before attending law school was thinking that myself and all of my classmates would have six figure jobs just waiting for us after graduation. That was hardly the case. I know many classmates who would have been better off (financially speaking) had they not forgone their already established careers to attend law school. I also remember being a summer associate at a Big Law law firm and thinking of how inadequate my background was when the majority of my fellow want-to-be lawyers summer associated attended first tier law schools like Harvard, Yale, Penn, Duke, Michigan, etc. Which brings me to my sad but true realization about law school: regardless of how good of a practitioner you may actually become, everything, at least in the beginning, is predicated on what school you attend and how you do once you get in.
So, if you have already decided that you want to work at one of the Big Law law firms (which have offices in just about every major city in the United States and Europe) and make six figures the moment you graduate, then the most important thing for you to do is get in to the best law school that you can. U.S. News and World Report ranks law schools and the higher the ranking of the school you attend, the more doors are opened for you. Once in said law school your next step is get on law review and then graduate in the top ten of your class. If you choose this route, I would go full-time as you will likely be spending a lot of time in the library (at least during the first year).
If, on the other hand, you have already decided that you are not interested in Big Law life and would rather become a sole practitioner, work for a small firm, do plaintiff's work, etc. then I would consider going part-time and managing your law school debt. When I graduated the average debt was somewhere in the neighborhood of $70,000 and I imagine that it has gone up since then. If that is the case, I would attend a school in the city where you are most likely to practice as your classmates will become an excellent source of work.
Last, don't bother watching the Paper Chase. Everyone will tell you that it is it is the quintessential movie about law school. It wasn't. Good luck and feel free to PM me if you have any specific questions.
