I personally found a lot from Lucretius Carus's "De Rerum Natura"[0]. It was important to popularize the philosophy of Epicurus. It describes three types of needs: 1. Necessary and natural needs: Sleep, eat, the other thing. 2. Unnecessary (from the individual's point of view) and natural needs: Have sex, eating over nutritious food, etc. 3. Unnecessary and unnatural need: Sports car, big house, etc. If you want to fulfill 2 and 3, it going to cost you something. With an abundance of pleasures will come pain. Epicurus was a man of another time and its solution, ataraxia[1], which is a form of extreme asceticism that would mean living like a monk basically, seems untenable today, but I personally got a lot from this on why work/life balance is important. His physic is also incredible. Like the concept of "Clinamen" [2]. The guy figured out quantum mechanic 25 centuries in advance.
