Look at the big picture, fight small battles.
I came across the book "War and Strategic Intent," a war book from the 1930s. Its analysis is very macro, examining issues from an extremely large perspective, yet when it comes to practical guidance, the conclusions are very small. It encourages us to undertake very small tasks.
This conclusion is quite subtle. Look at the big picture, fight small battles.
The big picture needs to be vaguely correct; the priority is correctness, and to ensure correctness, it often needs to be vague. Without a vaguely correct macro guide, detailed work often becomes futile.
However, in execution, one must start with the smallest actions. This needs to be distinguished from the macro judgment, focusing instead on the smallest battles and the smallest victories. Accumulate small victories to achieve a great victory.
If you only aim for great victories, first, the conditions may not allow it, and second, human nature is such that long-term setbacks can have a wonderful impact on the psyche. That book, after analyzing nearly forty years of strategic situations, encourages us to concentrate our attention and forces on attacking very small enemies and to only strike when there is an absolute advantage of victory.
If judged by the statistical concept of sigma, great victories are lower probability events. Sometimes, you need to achieve more frequent, smaller victories to reach the next great victory.
