Nursing Home Administrator?

I am interested in perusing a job of a nursing home administrator. I wanted to know more about the job. Is there any other jobs in the same field that are similar that I can also look into? I want to be involved in more of the paperwork side of nursing. I am 17 now and will be going into my senior year of high school. What can I begin to do to prepare myself for a job in this area? What schooling do I need? And if someone could give me a job description or some personal insight I would greatly appreciate it. Thanks :)
