After two years in San Francisco, I had to move back to my small(er) home town city because I ultimately realized there's little to no future for me in a city like San Francisco, despite making 250k/yr. I'd have to make at minimum $1M per year for a similar lifestyle (and even then, the stress of living in the bay area will reduce years from your lifespan... what's each year of your life worth to you?).
note: I made the assumption you didn't move to a village in a 3rd world country.
