Overall, this is a basic chapter about time management. It uses a single, but useful theoretical model. Little research is cited. The style is friendly and easy to read, but many claims are unreferenced and may be personal opinion, rather than advice based on empirical support. Layout is good, basic, with little use made of the learning features possible in a wiki environment.
Some paragraphs were overly long. Each paragraph should communicate one key idea in three to five sentences.
Some sentences were overly long e.g., "Grouping similar tasks is also helpful with time management as it allows your brain to continue on a certain wave length (Merchant, et. al., 2008), for example if you have two psychology papers due and one law paper, it would be wise to do the two psychology papers together as referencing, structure and sources are the same then to switch back and fourth from psychology to law back to psychology."
Some statements could be explained more clearly - see the [explain?] tags
The chapter could have benefited from a more developed Introduction or Overview, with clear focus questions relating to the self-help book theme and motivation or emotion.
Getting comments on a chapter plan and/or chapter draft could have helped to improve the chapter.
There was little in the way of additional learning features - the time management log is one useful addition
