Creativity is also an attitude, willingness to play with ideas, attitudes and possibilities, a flexibility of outlook, the habit of enjoying good, while looking for the ways to improve it.
Creative thinking is the process which we use when we come up with a new idea. It is the merging of ideas which have not been merged before. Brainstorming is one form of creative thinking: it works by merging someone else’s ideas with your own to create a new one. You are using the ideas of others as a stimulus for your own.
