Any work that is creative needs a dash of “I don’t know”.
When I sit down to write each post, I know that I draft it first and edit it later. I also know the skeleton of the idea that I wish to express. What I don’t know is how it would turn out. The choice and the rhythm of the words and the quality of the post are all a mystery until the moment of creation.
When you know exactly how something is done, you can write it down in a manual. It then turns into a standard procedure and fails to be creative. Further, it moves out of the human realm and into that of machines.
What makes any endeavour creative, and thereby human, is a kernel of mystery.
