Stephen King's advice to the writer: “One brick at a time!”

Because of the pandemic, many have heard or even read or re-read a famous Stephen King novel, thrill master, by title “The shadow of the scorpion”.
An apocalyptic story that foreshadows the end of humanity due to a disease that escaped a secret laboratory. In his preface King does not fail to bestow precious pills of wisdom to those who try their hand at writing, and he does it as always starting from personal experience.
There is a secret formula for writing a successful novel?
King has only one, work hard and patiently.
“If you have an idea, at some point another comes, a relationship is established or a series of relationships between ideas. Some characters (at the beginning little more than shadows) come forward, a possible conclusion is presented to the writer's mind (but it is rare that it has much resemblance to that expected at the beginning, once activated at the end). And at some point the novelist sits down at the table with pen and paper, a typewriter or word grinder”. And when you ask King how he writes, here is the decisive answer: “One word at a time”. Answer that, confessa King, invariably it is not taken seriously, but the author of “Shining” and many other masterpieces invites to consider the Great Wall of China: “One stone at a time, friends. That's all”.
