I've met a lot of students who said, "I want to apply to the Ivy League schools." But I've never met one of those kids who got in.
Being in love with the name brand of a college won't get you accepted. People who get into highly selective colleges don't worship at the altar of prestige. They want to learn, grow, and surround themselves with smart, interesting people. They know that if Yale or Stanford or Princeton says "No," they'll just fulfill those expectations for their college experience someplace else.
If you say things like, "I definitely want to go to an Ivy League school," you've got a bad case of name brand envy. The quick cure is to think about the reasons why you want to go to a school like that and start recognizing that there are a lot of schools that could give you what you're looking for.
