In other words, the experience is less important than how it affects your life and how it will affect your future experiences in college. Emphasize how these experiences have helped to shape you into the person you are today, and how college will be a continuation of that positive growth. Narrow your topic to a single subject. Don't try to write a broad, general essay on how your entire life has changed - you can't do this in one page. Choose language that reflects and relates to specific ideas.
Creativity engages the reader.
Don't be afraid to take risks with your writing. Use creative examples. Make sure your points follow logically. Utilize an outline to help you organize your essay in a logical fashion. Examples render your points in a concrete, understandable fashion.
