You explained the difference between the broad google definitions but that doesn't change my point that grit seems to be a strict subset of the actual definition conscientiousness which includes not only orderliness (which we both agree is unrelated to grit) but other things like achievement striving and industriousness (which appear to me to be the same thing as grit). You could have an artist that's low in orderliness but high in industriousness or high in achievement striving. Does grit add anything novel beyond these existing facets of conscientiousness?
