We have to be skeptical about "these methods" which, to me, seem more like PR myth they are trapped in.
Like Buffett saying that:
- he never set appointments (he works in isolation? he never goes to the doctor? He now flies with private jets? Everything has an impact on everything?)
- you never "leave large sums to your children" (My wife who works in asset management for (very) high profiles always rolls her eyes when earing that, replying "of course, to optimize the taxes you always create structures of foundations, so that they do not technical "get" the money but indirectly own the structure managing it.).
Basic math. 168 hours in a week. -100 for work, -49 for sleeping 7 hours. That leaves 2.7h per day. Probably lose at least an hour of that for basic human body related activities and general inefficiency. So 1.7h for being a family man and hobbies per day? Plus time spent driving to and from said hobbies? Plus the hundred small things we don’t track? Yeah it’s BS
I don't believe that every random set of 40 hours in his 100 would be something that he would be happy to pay someone else to do.
Successful people lie to themselves like this all the time.
