"Over the past nine years I have had the pleasure of hiring (and the displeasure of firing) new hires into their teaching careers. In watching teachers come into the profession some just "have it." Some seem to be innately programmed to be teachers. For others, it is a much more difficult road to travel. Additionally, there has been much awareness brought up about "teacher burn-out" and teachers not being able to survive this profession.
It has taken nine years of watching, listening, and observing to come to understand that there are two distinct differences between teachers that excel and love the profession, and those that do not excel and are prone to burn-out."
