The boy who expects every morning to open into a new world finds that today is like yesterday, but he believes tomorrow will be different.

Warner contrasts youthful expectation with the repetitive texture of ordinary life. The “boy” begins each day hoping for novelty, only to discover that daily experience often repeats itself (“today is like yesterday”). Yet the closing turn—“but he believes tomorrow will be different”—frames hope as a stubborn, sustaining force rather than mere naiveté. The line suggests that optimism persists even when evidence is thin, and that this forward-looking faith is part of what keeps people growing, striving, and emotionally resilient. Implicitly, Warner also hints at the human tendency to project meaning into the future: tomorrow becomes a canvas for possibility, even when the present feels monotonous.
