Thank you Mickey. Be nice, be helpful, be truthful. Let someone else be vicious. It's a waste of time and energy. Don't make enemies.
Friends are so much better.
Never be afraid to speak up and defend yourself and your principles. Don't let anyone change your mind when you know you're right. Don't let anyone involve you in compromising your principles or induce you to think that it's okay to do dishonest judging and play favorites. Be charitable with your time to friends and students. Be a roll model.
