The hanged man understands that he had to make a sacrifice in order to move forward - whether it was as a repentance for past wrongdoings or as a calculated step backward to recalculate his path forward. This time he spends here will not be wasted; it is a necessary step in his development. His inverted state can also represent the feelings of those who follow a spiritual path, as they see the world in a different light. You see things differently than others who don't understand the need to sacrifice. As you walk the path alone, this is a natural course of action for you.
