3. Make it personal and passionate: When you do start writing, don't forget that the main purpose of your essay is to convince the scholarship provider that you're the student they've been looking for. Answer the questions you've set out in your outline, but make sure every point you make is illustrated with a specific detail that shows you care about the subject.
Don't just mention that you work with disadvantaged kids; tell them how your love of soccer got you into coaching those kids. Don't just tell them about your acting awards; show how the stage helped you conquer your shyness. Putting your unique interests and perspectives on the page will go a very long way toward creating a memorable essay.
