I know of a couple of people I really trust that tried to explain to me how they feel when they try math or programming and it's more like a physical pain almost than frustration.For a lot of people writing prose is like this too (https://bessstillman.substack.com/p/on-writing-or-not). Back when I taught English to college students, it felt like getting students used to creating the smallest fraction of writing possible—getting them started—was a key skill, as was trying to teach the kind of free association that leads to deeper insights. Learning to manage frustration is of vital import to many people who want or need to learn to write better.
