Need advice on major (kinesiology/psychology/public health/study abroad)

<p>After watching numerous documentaries, reading books like Half the Sky, Invisible Children, etc.. I know that I want to help children in some way. I don't think I necessarily want to be a teacher, but I do want to help children. I am currently a kinesiology major and planned to do physical therapy after that, but I am not sure anymore. I took a psychology class and absolutely loved it. I used to think I wanted to be a physical therapist for a sports team and travel around the world with them, but that doesn't seem like it will help people as much as other jobs. Someone help me figure out a job that will allow me to travel (for/with my job), help improve the lives of children, and still make a decent amount of money to live. I am extremely interested in a job that will help make people healthy and more active as well that is why I've enjoyed kinesiology. I am not amazing at science, but if I know I will love my job I will put in the effort in science/math. I am also willing to do graduate and higher level schooling after I get my bachelors. I just can't decide if physical therapy is worth 2 chemistry, 2 physics, and 2 biology classes before I even get into my major. I still want to study abroad and do semester at sea. If anyone has any advice or experience in any of these fields please tell me. Thanks! </p>
