The brief
The Stoic philosophy, an ancient Greek school of thought, provides a timeless framework for living a good life by focusing on what truly matters.
Irvine argues that by embracing the 'three disciplines' of Stoicism - desire, action, and assent - individuals can cultivate inner strength and resilience.
The concept of the 'inner citadel' refers to a person's core values and principles, which serve as a fortress against life's challenges and allow for greater freedom.
Practicing 'negative visualization' and contemplating the worst-case scenarios can help individuals develop a greater appreciation for their current circumstances and reduce anxiety.
By setting 'life goals' and 'intermediate goals', individuals can create a clear roadmap for achieving their aspirations and make steady progress towards a fulfilling life.

Key ideas worth keeping

Happiness comes from living in accordance with reason and nature.
Inner strength is key to navigating life's challenges with equanimity.
A good life is not about external wealth or status, but about inner fulfillment.
