<p>Definitely do not write one about how your parents had to sacrifice so much for you! it’ll be written hundreds of times in your class of applicants. Here’s an idea if you’re going to explain your personal circumstances, zoom in on one day that you’re watching your little brother, waiting for your parents to come home. Analyze the seemingly mundane details and relate it to what its taught you. Responsibility, relate that to hopefully at least one EC where you were responsible. Leadership/independence, has it helped you mature? More often that people think, the best essays are usually close examinations of seemingly boring events, that are then related back to certain events that the writer has experienced. Its better if it is a unique boring event (^ such as that pizza place).</p>
