Think about what you like to do. Do you like being creative, interacting with people, face to face, online, via text? What makes you excited? Is it the thought of helping someone or building something? Do you want to make the world a better place, a prettier place, a friendlier place? What are your favorite subjects in school?
All of these should be taken into consideration when choosing a career. Depending on what your answers are to these and similar questions, then think about what environment makes you thrive. Large groups or smaller, intimate settings.
