<p>Penn and Yale are very different kinds of colleges. They are both fine colleges, but the "vibe " at each is very different. So, while I don’t know whether you and your sister are similar in terms of personalities, if you are, don’t assume that you sister’s unhappiness at Penn means you will be unhappy at Yale. </p>
<p>Seriously…though I think you may not believe me, I think it’s better to go into college with some doubts than to do so assuming you’re entering Nirvana. The pessimistic students are usually happily surprised. The ones who go into college assuming they will be elected to Skull & Bones and win a Rhodes Scholarship are the ones I worry about. </p>
<p>I went to a top law school that had lots of students who had gone to HYP and other top colleges. We used to joke that all the students who went to Princeton loved Princeton, but the rest of us couldn’t stomach them. About half the students who had gone to Harvard College loved it; the other half loathed it. The rest of us disliked the Harvard grads who had been happy undergrads and liked those who had been miserable and unhappy. All the students who had gone to Yale loved Yale, and the rest of us liked them. </p>
<p>You’ll be fine.</p>
