The first rule of writing a good personal statement is that it should always be interesting enough to capture the reader's attention from the start. The way to do that is to focus on a background story that is related to your chosen specialty.
Many Residency Applicants find it helpful to brainstorm specific events in their lives that led to their choosing of a specific specialty; therefore, collect your stories from the past and try answering specific questions about the event that has led you in this direction. Most residency applicants struggle because they cannot explain why they're choosing a specialty and so they get stuck.
Always ask yourself these questions before you begin writing so that you do not lose focus:
* What is the earliest memory that has sparked an interest in a specific specialty?
* What will it mean to me to get accepted into the program?
* What can I offer to the program that will help differentiate me from other applicants?
* What about my earliest memory has confirmed my passion for my chosen specialty?
Your memory doesn't have to be from childhood. If you can recall a memory/patient from your clinical rotation that has changed you and has confirmed your passion for a specialty, then you're half way there.
Side note: When writing a personal statement, be sure to write it in a narrative form by including details about the event that led to your chosen specialty. You can think of your personal statement, to some extent, as a story with characters. Each character having physical descriptions that will help your reader visualize the events as moving images. Thus, remembering where and how it started can help you write a human story that is intriguing enough to convince the reader that you're the best fit for the program.
Another important component of a great personal statement is focus and organization. When you're writing your personal statement, you need to remember that Residency Directors read hundreds of personal statements; thus, you should stay focused on your subject, move at a fast pace without losing your reader, and tie the entire personal statement together.
