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.
One thing I've been enjoying about working as a technical writer is that the minute-by-minute texture of the work feels right. Something about formatting text, faffing about with SVGs, trying to rewrite a sentence more clearly... it's just enjoyable in itself, and I feel at home with it.
...Working as a programmer was very much not like that. There's something in the rough vicinity of professional dev work that I do like, which I could probably label as 'iterative hobbyist tinkering with websites'. I like working on something with a strong visual component, and I like to be inside of a fast feedback loop, and I'm mostly interested in just somehow bodging through until it works. I'm not very interested in either the computer-sciencey side of programming — data structures, algorithms — or the software-engineerey side of making things run reliably at scale in a maintainable way. So maybe it's not surprising that the minute-by-minute texture of professional programming was just... kind of bad. Occasional fun bits when I got into something, but the background experience was not fun.
