Ratters pretty much covered it. Getting out, you start small, get paid a pittance and work your butt off.
Unless you are at the top of your class, you will have a tough job search ahead of you. My sister was about average for her class, she also obtained a masters in Medical Admin. and she had a tough time finding work.
I won't tell you not to do it, but I will tell you to think VERY hard before you do it.
First, finish your 4 year degree, and see how you feel about more school. For me, looking at 3 more years of finals really put a damper on things.
This is coming from a law school drop out. Law school is not that tough, anyone who tells you that is either lazy or stupid (or at a very tough school). I was at a top 50 law school, and I had the folks practically begging me to stay when I gave them my walking papers. I think that most schools (the exceptions might be ivy league types) want you to stay in (more money from tuition and future alumni) and will do pretty much anything to keep you there if you are a decent student. In fact my school had a policy where no one could "flunk out," a C was the lowest grade possible, as long as you did the required work.
Money was a big issue for me, I was out of state, and you can't work during the first year of school, so think that through very hard.
The main factors in my leaving were because I was in it for the wrong reasons, and I did not like the people. Don't do it unless you are sure you want to practice (or if you just like learning)!
As far as the people, it sickened me how competitive they were! I could see how willing they were to stab each other (or me) in the back just by looking into their eyes. I was at a liberal school, so their politics also sickened me. Some of the professors were also very condescending.
So think it through! If you really have the urge to practice law, and you can afford to go through with it, do it! It's not that tough.
If you have doubts about whether the profession is for you, or if you want big bucks, or if you will have a hard time affording it and supporting your family, don't do it.
