Music supplement at Yale after playing a few years?

One suggestion: From your very first post on this thread through your most recent one, your writing comes across as someone with a chip on their shoulder, someone who thinks they are far better than anyone else. And while that may be true, Yale looks for students who are humble, who are nice, friendly, approachable, student’s who reach out to others, student’s who would be good roommates. None of that comes across in your writing. Truthfully, your writing reeks of privilege and entitlement, it screams out that you would be a horrible fit for the campus. When you submit your essays, you need to ratchet down the attitude, otherwise your application will hit the reject pile before Admissions even listens to your masterfully played supplement.
