Undergraduate / Need help writing about short and long term education and career goals. [4]

I have no idea where to even start at. I don't think i have ever written an essay before in my life!! But i am trying to get into college after being out of high school for over 10 years. i am wanting to major in "health information technology" which is the same thing as "medical transcription" just a fancy name ;)

Any help would be appreciated!!
