Congratulations to all the surprise admits! Like shana22, I too had hoped that there would be more of you this morning, but nonetheless I'm very glad for you!
For everyone on the waitlist, hang in there. I agree with rhyme that Booth was probably conservative about its admits this year because of over-enrollment last year, so there may well be movement on the list in the months to come. Stay focused. I am crossing my fingers for you.
For folks who got dinged, don't lose heart. There are very very few people on these boards who have not been or will not be rejected from at least one school they wanted to attend. I will be. Admissions committees don't always get it right, or they're forced to make difficult decisions, and it's their loss - and in a sense ours, too, those of us who have been admitted. If you made it this far, you scored an interview. You had recommenders who praised you. You had a compelling profile. You had an advocate on the admissions committee. Good work!
Now, you too, stay motivated if you can, if this is what you really want. Another school this year or Booth next year or taking on more responsibilities at your current job -- wherever you end up, use this rejection as a motivation to do so well that in fifteen years Adcoms all over the country will be kicking themselves for not recruiting you with mad love and dollars.
