Stoicism is a school of philosophy which was founded in Athens in the early 3rd century and then progressed to Rome, where it became a pragmatic way of addressing life’s problems. The central message is, we don’t control what happens to us; we control how we respond.
The Stoics were really writing and thinking about one thing: how to live. The questions they asked were not arcane or academic but practical and real. “What do I do about my anger?” “What do I do if someone insults me?” “I’m afraid to die; why is that?” “How can I deal with the difficult situations I face?” “How can I deal with the success or power I hold?” [The Guardian]
