Chances of getting into Ivy League, i.e. Princeton?

Currently high school freshman, starting fourth semester (So not too much info yet). So far I've gotten all A's except for a B+ in gym ( I know... forgot to do a worksheet). I have a 4.56 weighted GPA (not really high i know, but hoping to get at least 4.7 by junior year), ranked 11 out of 251 (Not fabulous either). I got a varsity letter for swimming this year, but regretfully didn't join any clubs, although I'm planning to next year (and hopefully a lot of them). I pretty sure about NHS later on, and i took the SATs in 8th grade with a 1780 (obviously taking it again). I am going to take the AP Chinese test next week...and hoping for a 5. In the future I will take as many AP cles as I can (hopefully at least 8) and I plan on joining track next year. I am a very good writer, better than math. Then again, I haven't learned much math, and writing is more natural for me. However, I hope to improve a lot on math. I play the violin, I'm first generation Asian- American (does that have affect? i think so...) Looking back, there really isn't anything remarkable...but what are the chances of me getting into an Ivy League or top school, if I really pick up with the extracurriculars and the grades. If not Princeton, then maybe Brown, Dartmouth, UChicago, Carnegie Mellon, UCLA, or Northwestern? I'm very intelligent, but a bit lazy. Suggestions please?
