I just want to make a helpful point that was definitely made several times last year. Figuring out ranking and where you'll fall on that list is nerve-racking, and unfortunately we equate it with our likelihood of future happiness or value. Surely, picking the "right" #1 and matching to that site is the only way you win in this equation, and the only way you'll be happy next year. <- Wrong! (Thinking error, anyone?) First of all, statistically, half the the matched students will get their #1 and at least 80% will get in the top 3. Regardless of where your matched site was located on your ranking list, it is really, really likely that you're going to be super satisfied with your internship. So many examples popped up on this list last year of folks who said, "I matched with my (lowish choice), and I'm actually in love with the site now." For myself, I matched with my #3. Did it irk me a little when other people were like, "OMGZZZ I MATCHED AT MY #1!!!#$#$^%$%!!!!!" ? Yes. Did I briefly think about what precluded me from matching with my top 2? Yes. But that was all very fleeting because I MATCHED to an APA site and how can I not be grateful? Now that I'm in internship, I absolutely adore it and have several times reflected, "Wow, this totally should have been my #1." Because by nature the ranking process uses a system that implies 1 is better than 2, 2 is better than 3, and so on, it's so easy to fall into the trap of comparing yourself to others. If you don't get your #1, feel free to be annoyed at people who did (more specifically, people who are obnoxious about it). But let it go. Where you rank is not a reflection on you, particularly with this imperfect system. When you start internship in the fall, NONE of this will matter and you will have started a new, very exciting phase of your life where all you're focusing on is moving forward because you will not care at all about looking back.
So, in summary: Be considerate in your ranking, but remember that it is not the be all or the end all of your value and the value of your internship year!
