The Torah tells the story of how Joseph was in prison in Egypt. This is a model of how anyone in any situation can grow. After Joseph was released from prison he became a powerful ruler. That is because in prison he used his mental ability to train himself to master the attribute of total self-discipline. In prison he ruled over himself, and he went on to rule over the Egyptian nation.

Today, think of a difficult situation you are in, and consider how you might use this to develop mastery over self.
