This quote emphasizes the transient nature of life and experiences, suggesting that it is unrealistic to expect permanence in anything. Maugham points out that while it is foolish to cling to the idea of lasting moments, it is even more unwise not to appreciate and enjoy them while they exist. By acknowledging that change is a fundamental aspect of life, he encourages adopting a mindset that embraces this reality. This perspective allows for personal growth and a sense of freedom, as it frees us from the burden of expectation and disappointment. Ultimately, recognizing the temporary nature of our experiences can enhance our appreciation for them.
