Creative people are creative.
They strive to push forward the expression of humanities innermost depths because they have no choice, it's as essential as breathing.
I think that a big problem is that people confuse novelty for creativity.
Take Avatar for example.
Avatar is not a creative movie, almost every aspect of it can be traced directly to somewhere else. It's a well executed film, and it took a great deal of technical prowess to engineer. But none of it was the work of the soul. All of it's bright colors do nothing to tell us something about the people who crafted it, because they just deduced from what they know how to make a competent film.
But people call it creative because it's pretty and makes them feel good, the 3-D and CG is impressive and that's new so it's creative.
Creativity comes from within. If a creative work of art bares resemblance to another one, you don't care, because the person making it didn't care, and didn't pay it any mind. It came straight from their soul, it was just something that formed out of their control and demanded to be given voice. It doesn't matter if it was influenced by other works, because what really matters is that what it's saying is clearly said, not how it's said.
The execution is a means to an end so that it can stand as a whole, not the other way around
