NEW YORK

                                  
Why I Love It: This may seem like a cop out since I've lived in New York for a very long time, but I think it's all the more reason to include it. Ask most New Yorkers how they feel about this city and chances are they will say they have a love-hate relationship with New York. To live here is not easy. It's crowded, busy and far from being the cleanest (or clean at all, for that matter). Commuting can be a pain and sometimes you just never know who you're going to piss off today. Yet, I love this city. That raw energy I was looking for in London is what keeps me going, but I also recognize that I have to find my moments of peace and quiet or I will go crazy living here (I think it's the INTJ in me). New York has everything and for that reason, I love it. 
Why It's Worth Visiting: The energy, the views, THE FOOD! Oh man, this city has great food. From cheap, cheap, cheap dumplings to extravagant five-course meals, you can literally find it all. And if you can't find it, you may have a great business idea on your hands.
Favorite neighborhood: While everyone is going on and on about Brooklyn, I am all about my adopted borough of Queens. In particular, I love Long Island City (LIC). It's still somewhat undeveloped and industrial, but then you come across these great gems that make you feel like you've discovered something very cool and only a few (hundred) people know about it. Also, the view of Manhattan from LIC is pretty ridiculous.
