Communication Tip of the Day from Treat Consulting: GREAT MANAGERS ARE INNATELY ENTHUSIASTIC. Who’s your favorite…Teacher? The best teacher I’ve ever had was Elton S. Carter, Ph.D. (Communication) who taught at the University of Nebraska at Omaha when I was in graduate school. Dr. Carter was overwhelmingly enthusiastic about his work. You can’t inject enthusiasm into a teacher. The same goes for a manager. A manager’s enthusiasm for his/her work is innate – oh, and by the way, making sure employees are successful is a big part of his/her work. Seek enthusiasm in all.
