Undergraduate / Help with a self essay for application to a medical program [3]

I need to write a 1 page self essay for an application to the diagnostic medical sonography program at my school. Im having troubling getting started with format and topics to write about. It says I should include the following information:

My name, address, phone, email, and student ID (not sure how to put all that in a heading correctly)

A brief summary of recent, pertinent life experiences:

- education(high school to present)
- recent work experience
- related personal or family medical experiences
- volunteer work or community service
- hobbies or interests
- awards and honors
- memberships
(the only thing I have to write about here so far is that my aunt is a sonographer and thats how I became interested in this field. I never volunteered, I never received awards or honors... not sure what else to write about)

brief definition of my major field of interest, in my own words
brief explanation of my choice of career goal
brief summary of my self-perceived strengths and weaknesses
brief summary of my educational and career goals

Any help would be great! Thanks!
