What I want to do in life....

Everyone asks me what I want to be when I leave school; what I want to do in university and the sad thing I have an answer but at the same time I don't. My ideas that I have range from being a dance choreographer, to an author, to a psychologist, to a singer/songwriter/guitarist. I guess why I chose these things besides being things I adore with a passion is that they are mediums of which I've been inspired. So that leads me to explain the one thing I find them all to have in common which I would like to do after school; inspire people. That is the only thing I really WANT to do. I wanna be able to inspire people and touch their lives so much so that someone can genuinely say that if they had never been inspired by me then they wouldn't be the person they are today. I want to save someone; save them from this cold, dark and lonely world that we all live in because truth be told, it is cruel. I want to protect people from that or inspire them to do the same as I'm trying to do and make the cold, lonely, dark world a little brighter for someone. I want to be someone's hero, someone that they can look up to. Not someone like superman or batman, because they're just fictional and make believe; I want to be a role model for people, so that they have someone who genuinely wants to inspire them to be better. To say honestly, I only wish to make a change, even if it is a small one; making a slight change to someone's world and making them better for it; changing some event so that people don't feel quite so alone.... I just don't want to leave school and be "normal"; get a job, earn money, buy a house, get married, and die. I want to do more than just exist. So when people ask me what I wanna do after school? I say I don't know.
