The exact methodology in which he manages his life is probably less important than the fact that he's making a wide-sweeping effort in the first place, and maintaining consistency.
The opposite would be never writing anything down, never knowing what you're going to be doing on any given day, never estimating how long a task is going to take, reading books while making no effort to retain any information, etc.
We all dedicate energy toward transforming the natural chaos of life into order, even if it's just forcing ourselves to work a certain amount of hours per day, or re-reading paragraphs in books because we weren't paying enough attention the first time, or making grocery lists before we go to the store. These are things most of us do deliberately because we believe they make our lives better.
It's likely that there are certain things that he could be doing better, but I have no reason to believe that the structure he's set up isn't better than what he was doing before, and I think it's probably far more effective than the structure (or lack thereof) of most people's lives.
