That's actually not at all what he preaches. He's just an advocate of minimizing work you don't want to do and don't do the famous idle-work/pseudo-work the whole day (I can work 12 hours a day, adjusting power point slides, but that doesn't really make me productive).
I still have my issues with this approach. This only works in my opinion for reproducible tasks that are easy to explain. If have tried working with VAs numerous times. You need to calculate the time it takes to write a detailed brief on exactly what you want and usually have still to go through the project. Even with mindless tasks such as adjusting power point slides - if it is really important it makes sense to do it yourself. By the time you are done with it you know that you have exactly the product you had in mind free of any screw ups - except your very own. Unless of cause you have found the 'perfect' VA.
Don't hate on other people, because you didn't have had the success you wanted/expected from working with VAs. Maybe your approach was wrong? Also: automating redundant tasks doesn't necessarily mean using VAs!
I hate on people who promote subjective viewpoints / experiences as universal truth. The underlining idea ('don't define yourself by the hours you work') is certainly valuable but it is cooked up by a mixture of recycled self-help 'for the working professional' recommendations that are mixed with the promotion of unrealistic expectations.
