In "The Paradox of Choice," Barry Schwartz discusses the importance of self-restraint and discipline in various aspects of life. He illustrates this concept by comparing it to a personal guideline some might follow, such as limiting themselves to two glasses of wine during a social event. This practice emphasizes how setting boundaries can enhance our experiences rather than diminish them.

Schwartz argues that while it may initially feel restrictive to impose such limits, in reality, these rules help us maintain balance and make more satisfying choices. By applying discipline, individuals can navigate their preferences and desires more effectively, leading to a more fulfilling life.
