Different fields of law

<p>I've always wanted to be a lawyer, but I've only now discovered there are so many different fields. Can anyone explain to me what one does in corporate law and international law? How are the work hours and the pay? Also, I want to be in a field where I have plenty of opportunities to argue/present cases in front of a courtroom, do corporate/int. lawyers do that often?</p>

<p>Anyone?!?!</p>
