I believe at some point all writing roads pass through New York but you don’t need to live in New York City to be a writer. In fact, it’s probably a good idea when you’re starting out to avoid the city altogether. You only really need to live in NYC if you want to be in publishing. But writing and working in the publishing industry, while not mutually exclusive, are most definitely not the same thing. One requires a sharp mind, creativity, and the ability to work brutally long hours. The other is about writing down a bunch of made-up stuff.
