I think that ultimately any paper task tracking method that cannot be summarized within one or two pages of text is turning into that thing you do to procrastinate on actually doing shit, instead of a useful tool to help you decide what you want to do. Once you pass the preamble of "other ways I used to track tasks and why they don't work for me", this method passes that test. :)

Her method looks a lot like the old Bullet Journal method from before it turned into a major part of its creator's business affairs and became the sprawling ecosystem of rules and templates and books and discounts on paper/pens and Instgram influencers sharing the layouts they spent several hours on painting that is "BuJo".

Personally I prefer my variant of the Pomodoro Method from before it underwent a similar transformation; breaking one to-do up by the number of half-hour time units I expect it to take works well for me. Whatever works though. A nice notebook and pen work for me, too. Especially since I persuaded a few who had been bemoaning the excessive sizes of their fountain pen collections to send me some very nice perfectly-functional-but-unloved pens.
