Law school full-time is a three year commitment, I'm going to school part-time, keeping my full-time day job. I am in the 4th year of a 5 year program. For me it is good as I am a middle-aged guy in a technology job dominated by younger people, with the law, I picked a field where being a middle aged guy is an occupational bonus. I love law school but I may be the exception and not the rule.
If you love history and you love to read, law school is great. If you like getting up in front of groups of people and arguing, also a bonus. I had never done that before but it is mandatory at my school and I'm glad it was, turned out to be a great experience and will likely shape my career path going forward.
