Anyone working on their personal statements (whether just starting or polishing the final), I strongly suggest reaching out to David Busis (www.davidbusis.com). He's the guy who wrote 7Sage's personal statement add-on lessons (which you also should buy). I worked with him directly to help my essay along. We brainstormed about strong topics, organization, and articulation of key ideas. TREMENDOUSLY helpful. Reasonable hourly rate, and well worth it. He's not the kind of guy to milk the clock, and the thorough advisory letters and edits he writes for you offer you insights that will allow you to make fairly drastic changes to your paper. If you're committed to differentiating your personal statement, he is your guy. Any questions about my work with him, message me directly and I'll clear it up for you.
Good luck to all sagers.
