I have tried to keep on with my striving because this is the only hope I have of ever achieving anything worthwhile and lasting.

The speaker frames “striving” not as optional ambition but as a necessary discipline: sustained effort is presented as the sole pathway to work that endures. The line implies a long view of achievement—“worthwhile and lasting” suggests contributions measured over time rather than quick wins or public applause. It also carries an undertone of adversity: continuing to “keep on” striving hints at obstacles, fatigue, or discouragement, yet the commitment persists because the alternative is stagnation. As a credo, the quote elevates perseverance into a moral and practical imperative, linking personal effort to the possibility of meaningful legacy.
