"他不会过简朴生活就会一直成为奴隶"

Simplified Meaning:

If someone is not happy with just a small amount, they will always feel trapped and unable to enjoy life. Imagine a person who thinks they need a lot of money and fancy things to be happy. No matter how much they get, it’s never enough, and they always feel worried and unsatisfied. On the other hand, someone who learns to be content with less can find peace and happiness no matter what. Take for example, a person who lives in a small apartment and doesn't have lots of expensive stuff, but they enjoy simple pleasures, like spending time with friends, cooking a nice meal, or reading a good book. These small things bring them joy, and they don't feel the need to always chase after more. To apply this to your life, try to appreciate what you have right now. Focus on the small, good things each day instead of always wanting more. This way, you can feel free and happy without being controlled by endless desires.
