If you are poor, you can be good for yourself; if you are prosperous, you can help the world." It comes from "Mencius: Doing Your Heart". The original sentence is "If you are poor, you can be good for yourself; if you are prosperous, you can help the world." It means that you should take care of yourself when you are unsuccessful. When you succeed in your moral cultivation, you must work hard to benefit everyone in the world.
