Before, I was worried that my essay was something I would regret as the biggest weakness in my application. Now I feel like it's one of my greatest strengths.
Thank you very much for your editing. I especially appreciated your comments and critique. Your editing made my essay much more succinct and clear, and your critique helped me learn the weaknesses of my writing, which will help me in the future.
I wasn't sure if my essay really needed another edit, but when I saw the changes my editor made, I was so happy I had decided to try it out!
