Actually I think the problem is that he cares way too much. He has written himself too many sprawling storylines that all need to come back together in a satisfying convergence, which is very difficult. The further he gets in the story, the harder it becomes to continue. He’s also a perfectionist.

He’s a bit of a jerk for chronic underestimation of what it will take him to finish anything, and possibly for taking on other projects that further delay work on his magnum opus. But I understand procrastinating one important task by throwing yourself into work on different tasks.
