"It's not what happens to you, but how you react to it that matters."

"We cannot choose our external circumstances, but we can always choose how we respond to them."  Says Epictetus.

This quote by Epictetus conveys the Stoic philosophy that external events are often beyond our control, but our reactions and attitudes are within our power.  

Consider facing unexpected traffic on your way to an important meeting. While you can't control the traffic itself,  

you can choose to respond calmly, perhaps by notifying others about the delay or using the time to prepare mentally.  

This illustrates the idea of focusing on your response rather than the external circumstance .

It encourages a mindset focused on personal responsibility and mindful reactions . This is what quote encapsulates Epictetus' philosophy. 

 The importance of maintaining inner resilience and choosing constructive responses to challenges, rather than being solely defined by external circumstances.
