I have to agree that for a single person with no kids, LA has a lot to
offer–but it can also be a very “empty” place–without connections. We’ve known many who have come for the possibilities, and left completely unfulfilled, or even broken.
This is not to say this is or would be everyone’s experience, but, I guess, as in all things in life, it just depends on why you want to live there and what you are looking for. That said, since my wife works mostly from home, we do still enjoy going up for specific social or other events a couple of times a month or so.
I also think a person can create their own preferred environment wherever they choose to live. We entertain often, and have amazing conversations with amazing people, which often leads to amazing projects–so, even here–that end result is still possible.
