You may want to first decide on the type of essay, following which you can decide on the style (here’s where you can get creative) of essay. There is narrative essay, descriptive essay, expository essay, etc.
Every single word you type should be with this in mind: You want to give them a reason to say yes. This isn’t a writing competition, or an OP Ed piece for the NY Times, or therapy. It’s an appeal for admission to a college.
You were understandably vague about your topic. But be careful not to use your essay to instruct the reader. Remember, you want them to say yes to offering you a spot in their school. You want them to get to know you, not to be instructed by you. It’s about your personality, not about how smart you are— there are other parts of the application that will showcase that.
@simplycasperxp - Reread @bjkmom again. That advice is spot on. Imagine yourself reading something from a stranger and trying to decide if you want to spend the next four years with them.
