I ran across this blog a year or so ago and was pretty damn impressed. Apparently, this person came to L.A. looking for that golden egg and got a surprise instead. A really raw account of what can happen to anyone trying to make it in the big city.
Many people come out here looking with stars in their eyes or whatever, even if they don't plan to be in front of the camera. Did I tell you that major real estate company where I once temped had people performing "special favors" for a whole $13/hour? This was before the recession and by the time you eat and pay rent on a studio, there's not much left. Seriously.
As a native with roots in TX, I have a love/hate relationship with the city but in a nutshell, the blog offers advice on getting in the business of show and many others including some national resources.
