Developing physical strength and stamina is only one way that you exert self-control. Your inner drive to empower yourself as much as possible on every level is one of your greatest strengths and enables you to go far in this life, by the force of your own steam. You'd much rather do something yourself than depend upon anyone else to do it for you, or even take their help.
You have definite ideas about the way things should be done -- even things that are out of your domain. You like to reform and improve, to make things better. This predisposes you to being able to help others, and in fact you bring several skills to the table in this regard. You are not easily shocked. And you have such intense feelings, not all of them pretty. Despite their intensity and your fears to the contrary, you are not alone in these feelings. These are the gifts you can bring as a counselor, helping others in the processing of troublesome experiences and deep emotions. You are a natural competitor, and won't enter a game or contest unless you are fairly sure you can win. You must beware of obsessiveness, and also of being too wrapped up in yourself. You are a person who can accomplish a great deal in life.
