an idea is nothing more nor less than a new combination of old elements.

The materials which must be gathered are of two kinds: they are specific and they are general.

In learning any art the important things to learn are, first, Principles; and second, Method. This is true of the art of producing ideas.

First, the gathering of raw materials – both the materials of your immediate problem and the materials which from a constant enrichment of your store of general knowledge. Second, the working over of these materials in your mind. Third, the incubating stage, where you let something beside the conscious mind do the work of synthesis. Fourth, the

creative thinker.

the principle that an idea is a new combination, and the principle that the ability to make new combinations is heightened by an ability to see relationships

The second important principle involved is that the capacity to bring old elements into new combinations, depends largely on the ability to see relationships.

In this stage you have to take your little idea out into the world of reality. And when you do you usually find that it is not quite the marvelous child it seemed when you first gave birth to it.
