As for the OP...enjoy it, take it seriously and not seriously at the same time. Law school can overwhelm you and it shouldn't, profs and fellow students can be hyper-competative, cliquish, elitist douches. Your goal in law school is to learn a new way of thinking, not a new way of being, stay true to yourself, learn what you are taught and give back to the profs what they want...just dont give in to them, and you will succeed.
That is very good advice.
Not letting your professors and your peers freak you out is a large part of the battle in your first year. Realize that many of your professors have a vested interest in claiming that law school is the most rigorous intellectual endeaver imaginable because they got where they are by doing very well in law school. Always remember this: you didn't into law school because you're a dummy. You wouldn't be there if you couldn't handle what they are going to throw at you.
Congratulations and good luck.
