One adcom suggested that when you had a draft, you share it with someone who doesn’t know you well and ask that person to describe the person in the essay. If it doesn’t sound like you, go back to the drawing board.
Think about what you want to convey. Personally, I think that an essay that shows reflection and personal growth is compelling. For example, if a high achieving student can authentically write about a fear of failing and a simultaneous desire to take a risk that might lead to failure, it could be interesting. I like the essays that are stories because the details can describe who you are. Maybe there was an encounter that made her question what she’d believed. When it’s personal, it’s also unique.
One challenge for many good students – the ones who can write a good academic paper – is finding a voice that’s human and theirs. This isn’t abut big words or high literary style. It’s your story.
