Is there a creative mindset?

What is a creative mindset? Is it a state of mind more or less dependent on external factors or is it an internal trait, rather than a temporary state?

It might be something close to a state at first and when trained it can become a trait, more or less. For some it is something natural and a trait from the very beginning and others need some more training and creativity boosting activities to keep it going. No matter what, I believe it is something that everybody can take part of, as long as the internal and external conditions are nurturing it.
