Good luck, Brooke. If you are who I think you are, I believe I met you at the Hopkins and UCLA open houses, and you were very nice.
I'm in a somewhat similar boat, in that Chicago is a better fit for my interests but Harvard and Princeton are, well, Harvard and Princeton. If a "10" would be a perfect fit for what I want to study, then Chicago is an 8.5, Harvard a 7, and Princeton a 6, but ranked by funding packages they stand in the exact opposite order. Not really sure what to do, although I have promised myself that I won't be flipping a coin.
But for what it's worth, I think we should all just embrace our decisions (whatever they turn out to be), enjoy the years ahead of us, and not look back.
