Write a sentence succinctly summarizing who you are and what you are seeking. Avoid the use of "I" and aim for a more actionable sentence. For example: "Recent graduate with honors and accomplished cellist seeking a position as adjunct faculty in the music department with the University of Illinois."
Write five to six sentences that focus on your specific goal with this application. Use "I" in this part of your profile. Focus on showing your strong points rather than telling the recipient about them. For example, rather than "I am a patient and caring music teacher," try "I spent two years volunteering with a music therapy organization for disabled children."
Read your profile out loud to check for mistakes and run-on sentences. Revise and edit your profile as needed; it will be the first thing the recipient reads, and it must be well-written and interesting.
