When people talk about creative breakthrough, they often confuse two different things, using them interchangeably and confusingly.
The first is creative breakthrough that is personal, I call it iCreative. A new development for one creative or creativist individual, something that particular person has never done, or known, or been before.
You experience an idea or insight or achievement that is completely new for you. If you have an idea that you’ve have never had before, no matter how many people had the same idea already that idea is creative for you. iCreative.
The second is breakthrough that is historical, a new development for all humanity. Something nobody has ever done or known or been before.
I call this hCreative, a historical breakthrough for the whole of humankind.
