The world is supposed to be full of possibilities, but they narrow down to pretty few in most personal experience. There's lots of good fish in the sea... maybe... but the vast masses seem to be mackerel or herring, and if you're not mackerel or herring yourself, you are likely to find very few good fish in the sea.
The quote from D.H. Lawrence's "Lady Chatterley's Lover" reflects a disillusionment with the abundance of opportunities in life. While it suggests that the world is brimming with possibilities, personal experiences often reveal that these possibilities can feel limited. The metaphor of "good fish in the sea" implies hope, yet it also highlights a sense of scarcity, as most of the options may not be genuinely appealing or suitable for one's desires.
Lawrence emphasizes that many individuals might struggle to find satisfying choices if they do not fit into the majority. The feeling of being outnumbered by less desirable options can leave one feeling frustrated and isolated in their search for meaningful connections or fulfillment. This perspective invites readers to contemplate their own experiences with expectations versus reality regarding relationships and life opportunities.
