Seneca redefines poverty from a material condition to a psychological one. True poverty is not about the amount we possess but about the gap between what we have and what we want. Someone with modest means who feels satisfied is wealthy, while someone with great possessions who constantly craves more is impoverished. This insight places control over our sense of abundance directly in our hands. We can feel rich by appreciating what we have rather than constantly needing more. It's both liberating and practical, offering a path to satisfaction that doesn't depend on external accumulation. The wealthy person, in Seneca's view, is not someone with vast possessions but someone who feels content with their current circumstances.
