Do do the same thing this guy and do all the things you mentioned. I create cards on sundays only and i do anki every morning before i start working. It can be accomplished easily, sans children.
but that list is >8hrs of back to back chores (according to his estimates) for a non-work day without any of the ones your parent post mentions. I don't think that's realistic.
I imagine that the subject of the article is one of those genetic mutants who only requires 4-6 hours of sleep a day. They do exist, but are definitely statistical outliers.
Not needing 9 hours of sleep is the only real way to add time to your day.
