Giving this step the necessary hours now will pay off later.
Narrow your list of potential topics to your top one to three choices. If you’re having a hard time, try writing in different environments—coffee shops, your room, or a library, for example—and alternate between topics, and remember that at least at this stage, more words is better than fewer; there will be a step to polish your writing later.
Let me give an example: in writing about your budding interest in art history, you could write that you've always loved visiting museums, and how your art history course in high school solidified the interest. By focusing on details, you set yourself apart; many people love museums and could list some artists that they like.
Not many have taken the time to geek out about Edward Hopper on paper. Write how you speak: If your friends, family members, and teachers would describe you as silly, outgoing, and uninhibited, why would you submit a collection of essays all written in a formal, subdued tone?
This makes sense; your writing experience up until this point has consisted of essays on books you've read or concepts you've learned. Fight the urge to focus on your athletic practice schedule, the grandparent you admire, or the community service experience from last summer.
You may use these people or experiences as launching pads to discuss yourself, but that is all they should be. Is grandpa the reason you've always got a harmonica in your purse?
If you are writing a “why this school” essay, make a list of reasons why you are applying.
Do appropriate research to find strong reasons that show your genuine interest in the school.
If you have multiple essays to write in a short time, you can follow the appropriate guide for multiple prompts simultaneously, or offset it by a few days. You have the freedom to spend a few days figuring out which direction your essay is going to take, so take your time to think about what you want to convey in your essay.
Find four to five topics to begin with—you can ask your parents, friends, and teachers about what they find interesting about you in order to speed this process up.
