Google “how to hack the college essay”. You don’t have to follow the prompts so tightly, btw. While you can refer to what you do, you really want to show who you are. Personally, I think it’s easier to do this by writing as about an incident-- an interaction at your job that sparked you, something you observed in your bitds that made you reflect on something in your life or about yourself.
My advice is to whip out every essay you are thinking about then see what you have. Some parts may feel cliche, some like they are wasting space, and some may sing. You may end up melding certain parts into something new. Based on your posts, you write well and easily, so it’ll be about revealing who you are.
