...You might steal it.
How many times have you heard that one?
Let me clue you in - ideas are cheap. It's the EXPRESSION of the idea that is worth everything.
The story of Star Wars ("A New Hope" - Episode 4, for the purists) is hardly unique. Joseph Campbel outlines the plot in the index of "Hero with a Thousand Faces". The plot is repeated everywhere from "The Wizard of Oz" to the James Bond movie, "The Spy Who Loved Me".
The point is - it was George Lucas' unique expression of the story that caught people's attention.
That said - I can tell you EXACTLY what my new, secret project is. It's a cooking show.
Big deal. So what?
It's my unique expression of the idea - the "Steve Schnier Version" - the twisted, convoluted twist on the basic idea that makes the cooking show unique.
Another thing - how many ideas does a person have?
YOU'LL STEAL MY IDEA!!! (You've only had ONE idea in your whole life?)
That's a very sad - though interesting scenario. One solitary idea in a whole lifetime.
Ideas are cheap. They're everywhere. Take them, twist them - make something new.
