Here is something you need to know.
It is a quote that summarizes the creative process.
It describes what every writer, painter, composer, and creator of any type does every time they sit down to work.
It is clear, descriptive, and about the most precise instruction you will find anywhere.
Anything you might learn beyond this about how to do your thing is icing.
This is the fundamental construct.
Do something, then do something to that, then do something to that. – Jackson Pollock
