Summary
This quote suggests a conflicting relationship between sanity and happiness. It implies that maintaining one's sanity often requires sacrifice or compromise with one's happiness. In other words, the demands of maintaining mental stability might hinder one's ability to experience pure happiness. On the contrary, pursuing happiness might jeopardize one's sanity by disregarding the rationality or the consequences of one's actions. Consequently, according to this quote, it is difficult to attain both complete sanity and pure happiness simultaneously.
