The Eight of Cups suggests that there is stability and security in your life, but at a personal cost. You are probably unfulfilled by your current life. Depending on the rest of your spread, it may be a strong push for you to move on, and find the courage to strike out in a new direction. You will have to look closely at your work, your relationship, and your own beliefs to identify the source of your dissatisfaction, and then decide if you are willing to set aside some of your life's stability in order to find happiness.
