Lucky work ...

... Blood, Sweat, and Words.

Where grit must always be hidden, though, is in art. Art is by nature about hiding the struggle: the wrestle with words for the writer, with time and sound for the composer and performer, with the stubborn materials in the hands of the visual artist. Art is about emerging from that struggle victorious and showing not the least sign of strain, which is to say grit, for having done so. The artist in effect says, Look, Ma — you, too, World, look! — No hands! Art is about making things seem effortless, or so at the least is the art I most enjoy.

In other words, sprezzatura.
