I AM just reminding you of something I said some time ago: “A writer lives many lives.”
To create plots, the writer gets into the shoes of others and tries to see the world as the characters would.
Also, it is a time to learn – learn other views, other skills, other things, not learned in school or in the environment that the writer grew up in.
That is the amazing world that the writer lives in.
When s/he really gets into a story, there is no boredom ... just growing intensity sensed as s/he goes from one sub-plot to another.
As long as s/he lives, the writer will continue to learn ... for more learning enables him/her to make the plots more exciting, more realistic and richer.
