The quote by Epictetus, "No person is free who is not master of himself," underscores the importance of self-discipline and control in achieving personal freedom. It suggests that true liberty comes from within, indicating that individuals must have mastery over their thoughts, actions, and financial choices to live freely and make empowered decisions. When one is unable to manage themselves, they may find themselves constrained by circumstances, whether emotional, financial, or social.

Avery Breyer's book, "How to Stop Living Paycheck to Paycheck," emphasizes this concept by presenting a structured approach to financial mastery. In just 15 minutes a week, readers can learn to take control of their financial situation, breaking free from the cycle of living paycheck to paycheck. By gaining financial awareness and implementing small, consistent changes, individuals can achieve greater self-mastery and, consequently, improve their overall sense of freedom and fulfillment in life.
