How do you deal with "I should have applied there"? I am more than happy with the program I decided to attend, but also can't stop thinking of couple programs I ended up not applying.
I reconciled myself by reminding myself that if worst comes to worst and I end up hating the program I chose, I can always reapply next year, or the year after, to those shouldacouldawoulda schools. Nothing is ever set in stone.
