I find it very admirable that he can sit down for a week and just focus on one main subject. Personally, I get derailed all the time when I don't have a very well defined goal in mind. It looks a little something like this: I'll be reading a manpage and notice another manpage referenced at the bottom. So I obviously keep crawling this suggestions tree until I bump into a utility whose purpose is unclear. So then I'll go searching online to try and figure out what kinds of problems or use-cases it's meant to help with.
