Lol autumn, what do you mean what happens if everyone says you're a shoo-in and you strike out? Nothing! Absolutely nothing! No one cares! It's what you make of it.
I applied for behavioral marketing PhD programs last year before I finished school. At the time, I didn't really have a feel for the academic scene, nor did I have any real idea what field my interests fit best into. I wrote my SOP thinking my research interests were so great and new. I read faculty profiles loosely based on research interests they mentioned, tossing aside with youthful ignorance the red flag that I didn't quite understand a lot of the work the professors had published but firmly convinced my ideas tied into theirs. Even then, I received positive words from my network, telling me I'd definitely get in somewhere because I, like many here I'm sure, am one of those others seem to think is intelligent (for whatever reason, haha).
I didn't get in ANYWHERE! But guess what... no one cares! Nothing horrendous happens! Those who support you continue to support you. It was a humbling experience for sure, but it's those kinds of experiences that make you really do some soul searching and keep you down to earth.
Here I am one year later, taking the year off to work at my alma mater under some prominent faculty, with a far better idea of who I am as a person and what I'm interested in and applying for programs that I know are absolutely better fits for me than the programs I applied to last year were.
I don't mean to pontificate, I just graduated from school in the spring so what do I know really, and I'm sure this'll all turn out to have been an unnecessary worry; but I just wanted to share what I thought might be a relevant and helpful anecdote
