Think maybe Jeff represents one aspect of Trudeau’s own personality? I’m a commercially published book author, and I sometimes have feelings exactly like Jeff’s. And I know exactly what writer’s block is. It’s easy for armchair critics to scoff ignorantly at Jeff. These problems are real and and they are common. Even though Trudeau is extremely successful, he may still be expressing these concerns through the fictional character of Jeff Redfern.
Also through Jeff’s father, Rick Redfern, who’s also a writer. Genetics (or nature) + environment (or nurture) = the way a person turns out in life.
