Therefore, my brothers, be all the more eager to make your calling and election sure. Teaching is difficult. Don't get too discouraged if you don't have any students who can remember anything. Do, however, use it as an opportunity to remind yourself of the importance of learning to be a better and better teacher. I hope you will be a life long learner of the craft of teaching.

Better to learn a few things well than a lot of things poorly.
