We’re sure you have a lot of great qualities, you want to be a doctor after all. However, a personal statement needs to be focused and provide a few detailed explanations and examples of a few of your qualities. Listing every single positive quality you possess limits the amount of detail you can include about each one, which is less appealing for admissions committees to read.
To help you choose which ones to write about, think about which qualities you would want a doctor treating you to have and which of those qualities you can provide a strong description of in the body of your personal statement.
