My former colleague who is now a 2L at Harvard told me that law school was more like a 9-5 job than any other education he had pursued (which included not just high school and college but also part of a Ph.D. in philosophy). The way he saw it, you show up, you do the time, and you get your degree.
I think it's also like a 9-5 job in that it's kind of monotonous. Over time, I'm thinking less and less of why I am where I am and what I'm doing there. It seems ridiculous to think about being anywhere else or doing anything else.
Yet it's kind of a good monotony. There aren't really any crises or surprises. People are generally reasonable and pleasant to each other, which is quite unlike some of the jobs I've had in the past, especially when I temped.
Law school, in my experience so far, mostly consists of mature, intelligent, reasonable adults sitting around being mature and intelligent and reasonable, with a lot of sitting by yourself with books in between. But then what?
