So when you go to your first pitch meeting, keep that in mind. The buyer is your best friend. Assume the role of a counselor. They want to produce good movies that draw audiences and make money, and your project can facilitate those goals. If you can get yourself into that mindset, you're more than halfway there.
Nobody wants to read a movie about a movie by somebody who's only seen movies.
I'm not suggesting you need a life. I'm stating it. Sure, you can make it as a screenwriter with a film-school diploma and no practical life experience whatsoever. Plenty of people have. You must step outside yourself and observe the way people behave and speak under a number of various circumstances.
