Incidentally, Brooklyn is hardly a panacea. A girl in Brooklyn once kicked me out of her apt at 3AM after, while discussing life I accidentally revealed the size of my savings ("enough to travel around India for a few months"). (This was when I was an academic.) While Brooklyn is certainly better than Hoboken, there is no shortage of "artistic" types hoping to meet a guy with enough money that she can live the "bohemian" life without ever suffering materially or worrying about selling her art (and similar stories).
I've always said (though only ever to myself) that rule one of having a lot of money is: never tell pretty girls how much money you have.
It might also be rule one of not having a lot of money.
As the reality sank in, she asked me something along the lines of "how can you only have $XXX [her guess as to my net worth] in the bank?" She kicked me out immediately after I said "I could live for a year on $XXX." Once she concluded I was just a middle class guy, she just said something like "I'd like you to leave, this isn't what I expected."
Maybe I'm not a great judge of character, but I honestly was completely blindsided by this. (I'd have been more annoyed if it happened at 2AM rather than 3AM, of course.)
Specifically, she says she thought it was: "bold," "courageous" and "optimistic." Personally, I thought it was a huge disaster waiting to happen, but better than sticking it out at a job I despised.
When I say latent, it means that you felt more confident for a while before the move already, but it took the move, which brought anonymity, for you to externalize it.
This is why tourists act crazy, and even introverted shy people can act exuberantly on holiday. Or like your case, after a move.
