The primary thing when you take a sword in your hands is your intention to cut the enemy, whatever the means. Whenever you parry, hit, spring, strike or touch the enemy’s cutting sword, you must cut the enemy in the same movement. It is essential to attain this. If you think only of hitting, springing, striking or touching the enemy, you will not be able actually to cut him.
The McNamara fallacy, named for Robert McNamara, the US Secretary of Defense from 1961 to 1968, involves making a decision based solely on quantitative observations (or metrics) and ignoring all others. The reason given is often that these other observations cannot be proven.
The fallacy refers to McNamara's belief as to what led the United States to defeat in the Vietnam War—specifically, his quantification of success in the war (e.g., in terms of enemy body count), ignoring other variables.
The thing that you’re talking about though, which I’ve never seen a mature company really have a sustainable space for, is the “senior craftsperson.” They’re not pivoting at some point in their career to saying “I’m going to take what I know and leverage it through other people.” They’re saying “I want to get better infinitely at the thing that I do.” I believe that that’s possible.
You see it more in pure-art kind of careers. Like “I’m an illustrator” or “I’m a concept artist” or something, and there’s a need for that person being really fucking good at that one thing, and continuing to do that one thing. I think a lot of people can intuitively understand why that would be really satisfying for someone as a career path.
