First of all...what type of work do you do?
Secondly...SF is the shyt. Top five cities in the world son.
I bagged russians, germans, latins, ...theres massive black population in the neighboring cities.
Girls do seem stuck up. But they are not.
If you come at them like a little afraid you wont get much out of them. Its all in ur attitude. Not dress code, not status.
I run around SF like im the shyt, in my bummy workout gear. In dressed up mode. Im always talking to all of them. Proffesionals, hippies, etc.
Its super diverse. Super duper diverse.
Just last month i spoke with a nice black chick on the train. Yadda yadda. Didnt number close cuz i didnt want to. She.ran into me at the gym 2 weeks later and basically instadated her that night. Went out two more times, found out she is an architect, 23 yr olds, fit, but a jesus fanatic and pimples turned me off. But yea. Dont hate on a place cuz ur dying of thirst. Find a way around ur insecurities and start being the awesome person you are.
I will say this...there is gold digging vibe in almost everyone cuz its expensive but nice to live. But the gold diggers weed themselves out so its all good.
