I’ve never done a single thing I’ve wanted to in my whole life! I don’t know ’s I’ve accomplished anything except just get along.

The speaker’s outburst is a condensed expression of midlife disillusionment: a life spent accommodating circumstance, duty, and social expectation rather than pursuing genuine desire. The line contrasts “wanting” with merely “get[ting] along,” suggesting survival and conformity as hollow substitutes for self-directed achievement. Its plain, colloquial phrasing (“I don’t know ’s…”) heightens the sense of unvarnished confession, as if the realization arrives too late to be revised into something noble. In Lewis’s typical satirical register, such a complaint can also indict a culture that rewards respectability and steady progress while quietly starving individual aspiration.
