The Three of Pentacles mean that we have completed our apprenticeship and are ready to be a master. The card says that we have learned enough to work independently, to live or to love independently and so on. So the Three of Pentacles can mean that we have passed an exam, that we successfully managed a difficult situation, that we haven risen to a new phase of our development... But even though our pride in this is justified we shouldn't try to appear bigger than we are; there is always something new to learn.
