Epictetus emphasizes the importance of managing one's desires to achieve a fulfilling life. He suggests that individuals should focus their desires on what is within their control and recognize the futility of wishing for things that are unattainable. By aligning desires with achievable goals, individuals can prevent unnecessary frustration and disappointment.

In "A Guide to the Good Life," William B. Irvine elaborates on this Stoic philosophy, advocating for the cultivation of realistic desires that lead to contentment. The central idea is to simplify desires and focus on those that contribute to a meaningful existence, rather than chasing after unrealistic expectations that can lead to dissatisfaction.
