“So Good They Can't Ignore You” by Cal Newport, follows an attempt by the author to figure out what makes a career satisfying. Core argument, around which everything else builds, is that one should not follow one’s passion (since having spontaneous passion is rare), but should instead acquire “career capital”, that is “git gud”. From that career capital all the good things will follow: satisfaction through mastery, control through being valuable, and mission through extreme specialisation.
