Narcissm a way of life of a group of people

I had a conversation with someone today, and wondered afterward:

"How are you a narcissitic know it all who is not very succesful as defined by many, and younger than most people you attempt to boss around."

AHA!

The answer came to me, this person is a law student.

Law school, a place where being a confident narcisstic know-it-all is not surprising.
