The quote from D.H. Lawrence's "Lady Chatterley's Lover" reflects a sentiment about the nature of relationships and compatibility. While there is an abundance of potential partners available, the reality is that many of them may be similar, lacking the unique qualities that truly resonate with someone. This metaphor of fish in the sea emphasizes that not every person will offer what you genuinely seek in a relationship.

Lawrence suggests that if one does not fit in with the majority, which he likens to mackerel or herring, the search for meaningful connections becomes challenging. The implication is that finding a truly good match requires a deeper understanding of oneself and the recognition that true compatibility is rare among the multitude of ordinary options available.
