Creativity is a way of life. It is an ongoing process, not a series of isolated aberrations. It is a productive attitude developed by individuals throughout their lifetimes, not a random good idea that happens to work. Creativity is not a destination. We all do.
Creativity is very tied to low level stress chemical production.
Creativity thrives at all levels in the workplace. Everyone can be creative. Truly creative people are well balanced. It is much easier to be creative in a company who's policies invite it, but corporate policy is not a requirement for individual creative expression. Rate yourself creatively.
