Cherish everything you have, always with a grateful heart, remember not to rush to smell that fragrance, and look back at this life when you are old, there will be many beautiful fragments. Contentment is not clinging to what you can't get and ignoring what you have around you; Contentment is gratitude, openness, happiness and wisdom to enjoy life.
Obviously, if everyone can be satisfied with what he has, society will be stable and the world will be peaceful. However, there will always be some people in society who are restless and want to eat swan meat.
Such people are prone to stumble, and for them, the phrase "contentment is always a panacea". However, satisfaction or dissatisfaction depends on the occasion. In the old society, the poor ate grass roots and bark, while the rich ate bird's nest and shark's fin. Can you convince the poor to be satisfied on such an occasion? On the contrary, they should be encouraged not to be satisfied, but to struggle.
