“Know yourself and to your own self be true. You may find some day three or four years from now that you simply don't like engineering, or teaching, or architecture, or government, or the company you started with. You have little in common with the people you work with, and relative to your peers, you find your interest waning.At that point you have to muster whatever self-confidence you have, and every bit of your courage, and make the decision to do something else with your life. It is always better sooner than later to make that call.”
