Often creativity is stereotyped as a fluffy practice where one paints or draws or designs something but creativity also encompasses a great deal of innovation. In fact, it's more of a culture for being able to think beyond the box. A blog post on Not Another Quarter-Life Crisis brings up this idea as the blogger (a medical doctor herself), commented on the role of creativity in the field of medicine and why it isn't an integrated part of medical work culture.
In a way medicine is built on a foundation of formality, procedure and (at times) bureaucracy, but none of our largest medical advances were ever made from conforming to procedure. Is scientific research creative? It might not be the kind of organic expression that you might expect from the word 'creativity', but it does create advances in medical practice.
Understandably, in today's world, conformity has become the norm - accountability and rigid systems efficiency doesn't allow much leeway for ideas, let alone change. Medicine might have a completely different feel if the 'creative juices' were a part of practicing medicine and this can be said for many other fields where followed processes is encouraged, even in 'creative' fields such as architecture (where planning permission can stifle even the most humble of designs).
Along the lines of creative problem solving, an article by New Scientist cites a journal which found that people who feel anger brainstorm in a more unstructured way, consistent with creative problem-solving. Anger is often seen as a negative emotion, but examples of how controlled anger can be used for great effect are people like Gandhi and Nelson Mandela. Of course, how you express or use your anger is up to you. To quote the former: "You must be the change you want to see in the world."
