Should I apply SCEA to Princeton or ED to duke?

@mamaedefamilia Thank you for your response,
Boston sounds like my type of city. The air quality is also surprisingly good, which is a big plus for somebody from my location.
I have lived in small forested towns long enough to know that I can’t stand them for long ( We lived in Sweden for some time, which may be a plus for me too.).

Harvard it is then! In Iran, we have a saying for situations like this. We say “I want it, so It is 50% done. I just have to convince them.” (not sure if the humor translates, sorry if it sounds ridiculous.)
–About reading:
I see. one good thing about Princeton’s app is the favorite book and quote portion.
@exacademic thanks again . I understand that my fears are irrational. My mind is trying to convince me to aim as low as I can, because I am not very confident when it comes to things like this. I will, however; apply to Harvard.
The MIT cross-register, which I just found out about, is a GREAT opportunity! all the benefits of MIT classes without their disadvantages.
@alexandre I understand, Thank you very much for your concern for me. Thanks to you guys, I am now informed enough to not fall in the trap that is ED.
P.S : Silly me! I thought October is 30 day month. (in our calendar, all autumn months are 30 day). so I have more time than I thought.
P.S 2: I will appreciate it If anybody can spare the time / willingness to take a look at my essays.

BIG thanks to everybody who helped me in this thread. I wish you all the best in your careers / college apps / etc.
