Current MPP student at HKS lurking - good luck everyone!!
While you are waiting, I highly recommend setting a limit for how much you check GradCafe everyday. I was obsessive about it last year, and it didn't serve me or my mental health. Make sure you are treating yourself to some decompression time because the application season is stressful and the decision season is stressful. The waiting season is the only one where you have nothing to do to help yourself, so try to get outside, read a novel, cook a meal, etc. Harder said than done, I know. I'm rooting for all of you though!
I hope to see some of you at HKS next year or in the policy field one day!
