I've done the text file thing, and it’s fine. Up to a (very small) point.
What the author describes as their “workload” barely registers.
For context, for me, Things on any given day has over 100 individual actions, most of which are recurring.
By doing this, I can stay on top of an extremely broad surface area. There is no way a text file can handle the number of parallel work streams my (or really many) people have.
Broadly, for me these work stream are:
* Self Care
* Relationship
* Children
* Special Needs (IEP, SSI, Conservatorship, GGRC, Medical, Special Needs Trust, etc)
* Friends* Professional (BD, etc)
* Investments (Real Estate, Angel Investments, SEP, etc)
* Legal (LLCs, Litigation, Wills, etc)
* Financial (Quarterly and Annual Taxes in 2 countries, Insurance, etc)
* Home (Massive)
* Hobbies
* Vehicles
Without a serious amount of structure in the form of my todo system, there’s no way a person could manage this - certainly not with a text file.
Calendars very rapidly fall down for scheduled tasks that you can’t knock out the day of, they lack reminder functions, etc.
