I supply and market a certain line of cosmetics for many years that was very profitable. One day a major customer informs me that he is stopping to working with me and using another supplier. I was broken and crushed because this was my single source of income. Suddenly I remembered the well-known virtue of printing the books of the Maharal Tzintz and immediately contributed to the publishing of the books. Indeed, as soon as I contributed, I suddenly received a phone call from them that they decided to continue to work with me as they have done in the past!
