You sound the same way a lot of people I've known/heard sounded when they complained about how drugs ruined their life.
Except you didn't say 'drugs'.
How sheltered have you been? Or are you concealing something?
I'm not saying "Go pick up a drug habit" or anything..., I'm just sayin'...., WTF happened then? You minght think LA and NY are one of The Promised Lands.., but I've been to LA a bunch of times. I've seen it. Driven it. Walked it. Lived in LA county many years.
Dirty. NY probably is, too.
You would have to know someone in the first place in order for those dreams to come true easily. You could 'work it'..., but you'd have to bring something to the table.
Talent, for one thing. Unless you are a prodigy..., you have to refine your talents into something that they can work YOU for.
It is reciprocal out there in the real world. FYI.
So.., some places sex doesn't get you in. Talent can..., if you can handle that.., it can be LA or NY and all of that for journalism or any media.
You have to know someone or something to make it worth it for THEM. Even if you are standing at a machine in LA..., it is still dirty there. Dirtier than in other nearby cities in So Cal.
People who follow a dreams to The Big City sometimes end up in 'prostitution', one way or another.
That's all I'm trying to say.
