People are ambitious animals. They wont stop because of their immediate achievements. The good call for progress and the bad call for greed. Whats wrong with contentment? Do the elderly in the seventh and eightieth generation also need to make progress? Its time to enjoy the happiness of heaven and earth. Contentment and happiness may also be the same mentality of being at leisure as the elderly. If young people are like that, there will be no competitive mentality between them, and there may be no hatred without competitive mentality. No sorrow is joy, so people should be content and happy.
