Good novel is a conjunction of many factors, the main of which is, without a doubt, hard work. There are many things behind a good novel, but in particular, there is a lot of work - a lot of patience, a lot of stubbornness, and a critical spirit.
Mario Vargas Llosa
Stubbornness is a positive quality of presidential leadership - if you're right about what you're stubborn about.
The writer's secret is not inspiration - for it is never clear where it comes from - it is his stubbornness, his patience.
There's a fine line between stubbornness and the positive side of that, which is dogged determination.
