“Never try to change the narrative structure of someone else’s story, though you will certainly be tempted to, as you watch those poor souls in school, in life, heading unwittingly down dangerous tangents, fatal digressions from which they will unlikely be able to emerge. Resist the temptation. Spend your energies on your story. Reworking it. Making it better.”

So true… It is easy as an author to spend time reworking the plot or ending of a just-read book instead of writing on one’s own. I usually do that when I’m bored with my writing or have ‘plotter’s block’. Nice quote and nice blog.
