Twain's real point isn't merely that entitlement is unbecoming—it's that we mistake our arrival in an already-functioning world as some kind of cosmic debt in our favor. The world's indifference isn't cruel; it's simply the baseline of existence, and recognizing this actually frees us from the exhausting work of negotiating with an imaginary creditor. Someone stuck in a difficult job, waiting for circumstances to finally "give them a break," often wastes more energy resenting the unfairness than they'd need to actually change their position. Twain's wit here is a bracing corrective: stop negotiating with the universe and start negotiating with reality.
