The letters of Roman philosopher Seneca are a treasure chest for anybody wishing to incorporate philosophic wisdom into their day-to-day living. The book is profoundly insightful, it calls you to action, and it has the attitude that so defines the Roman Stoics.
There are several trapped, poor, millionaires, while there are several free “poor” people. This is one of the countless lessons I learned with Seneca, one of the most prolific Stoic thinkers alongside Marcus Aurelius and Epictetus. If you want to become a Stoic, you should read Seneca's letters.
"He is a great man who uses earthenware dishes as if they were silver; but he is equally great who uses silver as if it were earthenware. It is the sign of an unstable mind not to be able to endure riches."
“How much better to heal than seek revenge from injury. Vengeance wastes a lot of time and exposes you to many more injuries than the first that sparked it. Anger always outlasts hurt. Best to take the opposite course. Would anyone think it normal to return a kick to a mule or a bite to a dog?”
“If you live in harmony with nature you will never be poor; if you live according what others think, you will never be rich.”
