Format - plain bond paper; 10 or 12 pitch; on the top of the page center "Personal Statement"; paragraphs blocked or indented; keep it at one page; four lines below the last line of typing, add your full name, and signature above your name. A personally composed statement presenting reasons for desiring STA-21 participation and the applicant's professional/vocational intentions in a specific designator of the URL of the U.S. Navy. Comprehension of and motivation for a selected designator(s) of the URL are of significance to the selection board.

Address any other relevant information or substantial accomplishments not already covered. In addition, address any waiver requests, for example, age and time in service requirements, if applicable. Keep in mind, next to CO's Endorsement/recommendation, your personal statement is the most important document.
And here's what I have so far:
