My current Common App essay had to do with my routine of choosing my clothes every night before school, but a person who read it said that my essay should be focused on my future plans and my inspiration for following that path. Is this true?
No. It is not true. That doesn’t mean your essay is polished and ready to go, but that particular criticism is not valid.
I’ve heard that that’s the expectation for schools in the UK but not so much in the US.
