Doing one thing so well the world forgives you for doing nothing else.

means The process of narrowing your focus to one area, skill, or task in order to get really, really good at it.

from From Latin 'species' (a particular kind or form), which gave rise to 'special' — marking something off from the general crowd. 'Specialization' is a 19th-century formation, riding in on the industrial age's love of division of labor: the idea, notably pushed by economists like Adam Smith, that a worker who makes only the eighteenth part of a pin makes it faster than one who makes the whole thing. The word caught on as science, medicine, and industry all began splitting into narrower and narrower expertises — each one a 'kind' unto itself.
