College is what you make of it. If you go to a top-ten college, it doesn’t mean you’ll be a success, and if you goes to a no-name college, it doesn’t mean you’ll be a failure. The activities, students, faculty, environment, and opportunities provided by each college can be seized or ignored by every student, and only those students who seize as many opportunities as possible will end up happy, fulfilled, and successful.
Find a range of schools that’ll give you exactly what you’re looking for from an educational experience and apply to all of them. That way, no matter where you end up, you’ll get what you want. But saying that “you’ll only be happy if you go to Harvard” is unrealistic and ridiculous. As if the only happy or successful people in the world are the people who went to one specific university.
