I am the kind of person who believes that every choice has lead me to be where I am today. Good or bad, my decisions have brought me to where I am and helped to create the person I have become.

This is a really difficult question.  The things I would have warned myself against are kind of personal.  I would note though that if I had not made certain mistakes, I would not have found myself where I am.  So I guess I really would not change anything.  That's a pretty amazing revelation for me.

I'm not sure if there's anything.  I suppose I might warn myself against going and getting a Ph.D. thinking I would become a professor.  I didn't know that all colleges only want professors who will do a bunch of research whereas all I wanted to do was teach.  But on the other hand, the degree has opened doors for me so I shouldn't complain.
