Over at Slaughterhouse Studio, artist Lisa Skellings blogs about ubiquitous ideas. "We all think our ideas are special, and unique. Guess what. (drumroll) They are not."
I've seen a similar attitude on screenwriting forums where someone invariably posts, "Ideas are a dime a dozen."
Some of our ideas are special. That's where art comes from.
Bad ideas are a dime a dozen. Good ideas become multi-million dollar franchises.
The trick is to recognize the difference.
