You can’t think while creating. Creativity is the opposite of thinking. The thinking comes after. Creating is a living experience. Thinking gets in the way of living. Thinking is an act of reflecting or analyzing, while what creating requiers, is a living experience.

Dancing (as well as performing), works pretty much the same.

I think it has something to do with how meaning is produced or generated. It’s impossible to think your way into meaning. Meaning isn’t the result of thinking, but rather an essence emanating from doing and being. Thinking happens too far from where being is, it arrives late to the party somehow, it can only have a reflective quality, never a generative one.
