What is imagination/creativity to me?

Imagination is creating and visualising inside your mind. It is thinking of the impossibles, without any action done. It is what you are imagining, thinking, longing, craving, and your desires. It is practically thinking what you want.
Creativity is the process of thinking and imagining. It is the ability and an act to think out of the box, with unpredictable and unique ideas, and to be original. To me, it is considered as a skill, and a talent. Everyone is creative, just that in different ways.

Creativity is not something that can be learned out of textbooks. I believe that through more applications, it is possible to be trained.
