Dickens isn't offering mere sentimentality about appreciating small things—he's making a mathematical claim about how human existence actually accumulates. We often wait for grand moments, believing they'll define us, while overlooking that a Tuesday conversation with a neighbor, the particular way morning light hits your coffee cup, or how your child mispronounces a word these are the actual *substance* of a life, not interruptions to it. A parent who frames bedtime stories as trifles, rushing through them to reach "important" adult tasks, discovers years later that those moments were the sum—the whole architecture—of their relationship with their child.
