I quite liked your licking metaphor/symbolism. In fact, if I find out that something tastes good after licking it, I'll go even further. I swallow it. Ha ha.

My intuition is that creativity is a more of a feeling one has, rather than the result of some teaching method or cultural background. It seems very closely related to one's interests and also the novelty effect. Just think about the first time you experienced something, like a great song or your first love. The mind is just bubbling with thoughts. How can that feeling be experienced again with the same object like it was the first time? It can't. It's never the same as the first time. Even if we can mentally forget, the subconscious somehow remembers it's had that experience, so it isn't fresh anymore.

So, yes, you need to make connections between existing things to come up with something new, but once the fascination with a thing dissipates and it becomes familiar, any further creativity in that area quickly dies off. Our interest just moves on.

Perhaps the really creative people are just the ones who have this ability to see familiar things with ever fresh eyes?
