I'm a very creative/imaginative person. What career would be right for me?

Ever since I could imagine, I have always been debating on jobs that would suit me and have been bouncing back and forth between them. Now since i'm going into 11th grade I've realized that it would be a good idea to pick a career and set my mind to achieving it. The thing is, I don't know what career. I'm very imaginative, I love to write, I pay very close attention to detail, i'm a perfectionist, I am compionate, I love helping people, and I spend most of my time reading. Additional things (but not very important) are that I would like to travel the world and would like to leave my mark on this Earth by doing something positive. Any suggestions as to what my career path should be? Any answer is appreciated. Thank you for your time!
