You know early on in life what you want and you are willing to work hard and overcome many obstacles on your way to achieving it. You don't like to be told what to do, and you prefer to become your own authority, self-directed in every way. The concern for security and safety is the underlying motivation for many of your most important decisions; you do not want to depend on others to take care of you.
This helps you take the long view when you're planning your life and mapping out your goals. You have both discipline and endurance, which will carry you far in this life. Although you have a natural distrust for people in authority and probably don't seek positions of leadership, you may be thrust into such roles as you mature, due to your self-discipline, dedication and serious nature. You will handle these types of responsibilities very well. You are committed to transforming and improving existing structures; by simply applying your effort and focus, the changes seem to occur quite naturally. Devoting yourself to a cause can do much to further it. You're in for the long haul.
