Here is some great career advice for introverts. I remember reading somewhere that while extroverts outnumber introverts in the general population (by a margin of something like 3 to 1), among lawyers, there are actually more introverts than extroverts.
Introverted lawyers/law students may also want to check out a recently published book called “Quiet, Please: The Power of Introverts in a World That Can’t Stop Talking.” You can read an interview with its author Susan Cain here.
