the art of being exactly right while everyone else is approximately wrong
means the quality of being exact, accurate, and finely detailed, with no room for vagueness or error
from From Latin 'praecisio,' a cutting-off, from 'praecidere'—'prae-' (in front) plus 'caedere' (to cut). The same blade lurks in 'scissors,' 'concise,' and 'incision.' To be precise is, quite literally, to have trimmed away everything that isn't exactly right.
