<human>: Can you give me the gist of the text in a nutshell?

I have lived a slightly unfulfilling life thus far and am about to graduate from a college that I hate with a degree I don't want (sustainable business). I have bounced around from career to career and can't seem to settle on one that I really love. Chef, priest, high school Spanish teacher, farmer; none of them panned out. But the whole time I have felt drawn to the tv/film industry, and I feel like if I never give this a shot, I will always be wondering "what-if?"

So I want to move out to LA sometime within the next 18 months, and I am wondering if any of my fellow redditors could spare some advice. A little about me:

~ I have quite a bit production experience, but most of it is in theatre (stage managing, production design, etc.)

~ I am prepared to have my soul crushed, and I take blame graciously.

~ I am willing to do almost anything, and if I can't do it, I will learn it.

~ I also plan on bringing my girlfriend with me (her job transfers fairly easily)

~ I'm hoping to have a couple grand saved up before I move (mostly living expenses/rent)

So some things I want to know:

-Should I have work lined up before I move?

-What are some good neighborhoods to live in? (Safe and cheap)

-Is it absolutely necessary to have a car?

-How difficult is it to find P.A. jobs?

-Anything I should absolutely know before I get there? I am being as realistic about this as possible, so feel free to give it to me straight.
<bot>: I am leaving my banal life in the midwest to try and get into tv/film/radio production. Please spare any advice/wisdom you can.
