By the time I left I really hated working there. I tell some of the story here: http://j2labs.net/blog/2010/jan/11/economies-pools-and-piss/
Anyway, when I moved out of the apartment I had, near Wall St, I threw out my suits. I told myself I'd never take a job that required a suit. The suit felt like a hollow nod between business men that the appearance of success was to be regarded just as highly as the ability to succeed.
I'm less hostile to suits today, but I much prefer to do business with the types of people that also don't like wearing them.
