You're the master of your fate and the captain of your soul.
While your character is formed by circumstances, your own desires can do much to shape those circumstances. Thus, you have the power over the formation of your own character.
Nature is always at work around you. Your character and destiny are her handiwork. She gives you love and hate, jealousy and reverence. You have the power to choose which impulse you will follow.
You can at any time decide to alter the course of your life. No one can EVER take that away from you. The greatest power you possess is the power to choose.
You're the master of your joys and your sorrows.
