The author, Sophie Kinsella, suggests that finding happiness in life is related to understanding that everyone has challenges, regardless of how perfect their exterior may seem. When observing others who appear to have it all together, it’s essential to remember that they, too, face struggles and difficulties behind the scenes. Recognizing this can help alleviate feelings of envy and isolation.

Conversely, when individuals confront their own challenges and feel overwhelmed by their circumstances, Kinsella advises them to remember that their situation is not the entirety of their life. Everyone experiences ups and downs, and often, brighter moments are present even if they are not immediately visible. Understanding this provides a more balanced perspective on one’s own struggles.
