Always remember you could be wrong. This is the essence of humility. And if you're thinking you're better than someone else, because of your résumé, or what projects you've worked on, or what school you went to, or where you grew up, or the color of your skin, or your gender, or your religion, or for any of the myriad other reasons we silly human beings come up with, then you're definitely wrong. On the other hand, no one else is better than you, either. Learn to be alert to your ego. Don't let it get away with anything. And if all that fails, learn Lisp! (Just kidding! Lisp users have a reputation for arrogance that is, alas, perhaps not entirely undeserved.)
