Ms Schneller quotes a 1983 movie memoir.  I'll go one better. 

I was 17, machete in hand, ready to hack out a career path for myself. But which path? Radio? TV? Newspapers & magazines? Movies? I came across a new  book, "Only You, Dick Daring," by scriptwriter Merle Miller ("Scriptwriter? Yes!") It was one of the most outrageous, painfully funny books I have ever read. In my life. I read it in 1964, so that's saying something. A classic about faulty or no-logic thinking, ineptitude and excess. Subtitle of the book: "Or, How To Write One Television Script And Make $50,000,000." 

Just read about the making of Star Trek, The Motion Picture in "25 year Mission," a brand new oral history on the Trek Phenomenon. A classic about faulty or no-logic thinking, ineptitude and excess. 

Dozens of writers, producers and directors would likely agree it's a miracle anything gets to the screen.

The OTHER Golden Rule: "Nobody learns anything." On or off the couch.
