Promotions are simultaneously the happiest and most frustrating events for professors. They are the happiest when seeing the joy in the students who advance. They are the most frustrating when listening to the resentments from those who do not.
So here is a little note to all who do not get that promotion this time: ranks are not objective. Winning this or that title doesn’t guarantee promotion. Also, beating this or that guy in the gym doesn’t. And, being better than the guys who did get promoted doesn’t guarantee either.
Why? Well, people have different potentials. Some come in young. Some come in strong. Some come in with experience, and others come with poise. A persons rank is reflective of their skill in relation to their potential. It is not a comparison of skill between two different people.
