“That is my right work”
The phrase names the work Ruskin believes best fits his actual abilities, separating a personally appropriate vocation from duties he feels forced to assume by public distress.
Source note: Time and Tide by Weare and Tyne, Letter XIII; Project Gutenberg #31196. “Right work” refers locally to Ruskin’s painting and study of nature, so the record is about vocation and fit rather than a universal career prescription.
