Scholarship / Need help on a scholarship essay on educational and career goals [3]

Hi my name is Sarah Norris and I am having trouble getting started on a scholarship essay and I was hoping that I could get some help getting it started. The instructions/prompt are to explain in detail my future educational and career goals. I am allowed a maximum of 4,000 characters. I don't even know where to begin. Right now I am an E.M.T for a local fire department. I am hoping to get a scholarship so I can further my career and become a paramedic. I also have already completed the courses I need to obtain a degree in this field. I just need to get my paramedic license to get an A.S. degree in Emergency Medical Services. Can you please help me with this essay. I just don't know where to begin!
