studies for a Large-scale work

I’ve been reflecting on the difference between writers and artists. Mostly artists are in interested in the process even they’re impatient to finish their work. While writers are mostly interested in writing “The End” (with a sigh of relief) on the final revision. I saw a Constable exhibition in London a few years ago. Many of his studies were like finished paintings. I’ve started to wonder whether multiple drafts are similar to preparatory studies for large scale paintings.
