To keep myself in check, I use goal-setting exercises regularly. Each quizzer has their own goals, and each team must have common goals among its quizzers. As a coach, I can hold the quizzers accountable to those goals. I review these goals every month to see if the quizzers are staying on task or, if perhaps, my goals have replaced their goals and has now become more important to me then to the quizzers. Some quizzers need to make their goals a little higher, some a little lower.
Goals are much more likely to happen than wishes or hopes.
As a coach, I believe my greatest measure of success is if my quizzers reach their goals. As a mentor, my greatest measure of success is how many of my former quizzers serve God. Tell each of your quizzers weekly that you care about them and their problems, and they will open up to you as their mentor and friend.
