I don't understand why people still
a) think that "knowledge professions" are some kind of unicorn job where special snowflake sauce is required, and it's obviously totally different from those gritty "manual labour jobs" and you have to constantly set yourself apart (how arrogant is that?!)
b) purport this strange notion that psyche has little to do with the body. Digger won't dig? Just whip'em, it'll work for sure.
