"It's a good school."
That's got to be just about one of the most banal (yep, somebody's bringing out an SAT word!) reasons you can give for being interested in a college.
Don't tell a college that you're applying because, "It's a good school." When your college interviewer asks you what got you interested in Yale or Duke or USC or whatever the college may be, don't tell them, "It's a good school." Citing that as a reason to apply is akin telling your parents you want to marry someone you barely know because your friends say she's "pretty cute." The interviewers, the colleges, and your counselor will all think that you (almost certainly) know little about the school other than the fact that it's famous. You'll be outing yourself as someone who hasn't thoughtfully considered your colleges.
Instead, try this. "It's a good school for me."
When you can follow that answer with a detailed description that backs it up, it's usually a sign that you've done some thoughtful college soul searching. It shows that you've considered what you want your college experience to be like, what you hope or expect to gain from your time on campus, and how you see yourself learning and contributing while you're there.
Spend the majority of your college search seeking out the colleges that will fit that statement. You'll inevitably spend as much time thinking about yourself as you do about potential colleges. That's a good thing. And once you identify the schools and the reasons why you're picking them, you'll have a lot of things to say after,
"It's a good school for me."
