First thing to look at is 6 paragraphs. Paragraph number 1 and 6 are the opening and closing. They will be telling what you want to say and tell what you said. They will be very similar just rewording the same information. Next you have 4 paragraphs for the body of the essay.
What does the education mean to you personally, do you have someone in your family without a high school education, or have all your family member graduated high school and you want to continue the tradition? If you have a family member that was a high school drop out, what does that mean to you? Are you motivated to learn from that mistake? What are your plans for the future? Do you need a diploma to achieve that goal?
Try to come up with 3 points to focus on. Tell a story, give specific examples and relate back to yourself personally explaining the relationship and how it motivates you to work harder and achieve more. End with a challenge to others so they do not give up, or end with a dramatic quote.
