Creativity is thought to flow from such people with little or no effort. Certainly an inspiration may seem to come out of nowhere. But this is far from the truth. As researchers study the nature of creativity they discover a very different picture. Here we find evidence that creativity is very much grounded in the individual's knowledge and how he or she combines that knowledge of often dissimilar concepts to create new perspectives.
Creativity is very dependent on given ideas, cultural assumptions and general knowledge.
In other words, although creativity may seem to come like magic, it is really grounded in a vast well of knowledge and experiences. In fact often the challenge of the creator is to sort out the irrelevant material from the usable, not an easy task as in order to combine old ideas into new creations one must still be open to what seems irrelevant and yet may be just the piece needed for the desired result. An occasional creative inspiration won't get us far. Instead we need a deepening understanding of our area of creativity as well as increasingly refined skills in order to create. Without knowledge we cannot draw from our memory to find unique and interesting ideas or objects to pull together.
