From the Preface to "Sherman: Soldier, Realistic, American" -
To place the position of battles and trace the action of battalions and batteries is only of value to the collector of antiques, and still more to the dealer in faked antiques. Those who believe that exactness is possible can never have known war, or must have forgotten it. And even if by supernatural means we could recreate the action in such detail, it would be historically valueless. For the issue of any operation of war is decided not by what the situation actually is, but by what the rival commanders think it is. Historically and practically, it is far more important to discover what information they had, and the times at which it reached them, than to know the actual situation of the "pieces." A battlefield is not a chessboard.
Emphasis added. "For the issue of any operation of war is decided not by what the situation actually is, but by what the rival commanders think it is."
The organizational structure you put people in has a huge bearing on how they perform.
If a person is in a small town, they'll act differently than a large city.
It's not that they'll consciously choose different options, per se - instead, they'll naturally have different stimuli.
Add in different constraints and incentives, and you get very different behavior.
Why did the Romans conquer so much?
What if you decided you were going to accept whatever happened to you ?
What if you accepted every moment just as it is? How would your life be different?
Does that sound scary, or foolish?
What does acceptance mean? Most people think that it means giving in, or giving up. Resignation to a horrible fate. You may wonder “How can I accept the horrible things that are happening to me?" and "If I accept them, doesn't that mean I'm hopeless and not trying to make it better?"
No. that’s not what acceptance means. Accepting does not mean giving up.
