Contentment is natural wealth, luxury is man-made poverty - Socrates

Let your heart be as you wish without losing it. Contentment is always happiness, and one does not want to think outside of it - Kuang Zhouyi

No disaster is greater than not being satisfied, and no fault is greater than desire, so contentment is always enough. ——"Laozi"

If anyone is truly content in his heart, he will be able to obtain all happiness. ——"Five Volumes of Books"

When things are satisfied, the heart is always happy, and people have no pursuits and high standards.
