Article upholds author of "4 Hour Work Week" as an example of an ultra-remote worker. Someone who made it rich selling supplements of questionable benefit and with much self promotion may not be the best anecdote for remote workers.
I think the aspect he offers to someone that wants to stay at the job but do some remotely is still very applicable to today's WFH situation.
The Parkinson's law and 80/20 rule are great. I think more could be written about that idea of a FAQ that is maintained by customer service. This could be more broadly applicable to any documentation or how to material both internal and external to a company. Knowledge management is not an easy task.
Read the book if you haven’t, it’s all in there. You’ll get much more benefit than finding out about the supplements I suspect. I recall something about him introducing himself to people as a drug dealer when asked what he did for a living.
