is there something as first thought ? the primary thought which is laid down on paper in a sketchbook or in other mediums.

I will stick to the experience of creating the same in the sketchbook and then repeating the thought, the idea multiple times in the sketchbook.

I kept coming back to the first page and something which i can not figure out, or place the right word for it, what is it about the first, primal mark, as it is prior to correction.

The mark post the first thought, is the improvised thought. It is trained in nature. It is after the first thought. And there is nothing before the first thought.
