In "The Paradox of Choice: Why More Is Less," Barry Schwartz explores the idea that having too many options can negatively impact our well-being. While choices are generally seen as beneficial, an abundance can create anxiety and dissatisfaction. People often struggle with decision fatigue and regret when faced with numerous alternatives, leading to a decline in happiness.

The book argues that we do not easily forget the options we've rejected, which can enhance feelings of disappointment and self-doubt. Schwartz suggests that simplifying choices can lead to better satisfaction and mental health, as it allows individuals to focus more on their decisions rather than being overwhelmed by possibilities.
