I had a student that I found very challenging, and I felt frustrated that nothing I tried seemed to help. I decided that if I (and the rest of the staff) did not know how to help him, I would at least do my best not to do anything to make his situation worse. I tried to be as patient with him as I could, and I was careful not to yell at him or insult him. He is a very successful Menahel today.
It is good to remind yourself that real success is doing the best possible job for your students according to where they are “holding” at that time. Some people foolishly think that the teachers who have the easy students are the best ones. In truth, those who deal patiently and wisely with the difficult students are the best of the best.
