In today's society, we have enough material needs to meet, and people's sense of competition is constantly increasing, which makes everyone strive to achieve contentment and embark on the trend of dissatisfaction. People often say: contentment is always happy. In ancient China, there was an anonymous poem: "Running around all day just to satisfy hunger. I want to wear clothes and marry a beautiful wife when I am full and warm." . (This poem is dissatisfied with criticism, which is inconsistent with the original intention, but this quotation is worthy of recognition. ) contentment and discontent lie in one thought. Only by highly unifying contentment and discontent can we get real happiness. Therefore, we should be content with contentment, not content with learning. The so-called life satisfaction means that if you want to be happy in material life, you must be satisfied, and you can't blindly pursue higher material enjoyment. We live in such a stable age, and we don't lack food, clothing, housing and transportation. Why should we ask too much for a higher-end life? Villa, Mercedes-Benz, high salary and rich family are not for everyone. What if we pay too much attention to the immutability of our own matter? Demanding will lead to our mental overload and depression, which will lead to many excessive behaviors and even criminal behaviors. As the saying goes: contented people are poor, but they always laugh, while dissatisfied people not only frown when they have everything; (Thoroughly, well) People who are satisfied often have their own achievements, and those who are not satisfied often have everything and have a headache. Knowledge is the bridge of human progress. This sentence should be deleted because it is absent-minded. For knowledge, we should be content with contentment, keep making progress and forget to learn. Only in this way can people make continuous progress and have more knowledge. Gorky once said: "Knowledge is as precious as human blood. Without blood, people will be weak; If people lack knowledge, their minds will dry up. " Yes, in learning, we must constantly explore, discover, supplement and absorb in order to have a higher understanding. Reading has broken thousands of volumes, and writing is like a god. Even saints say so, let alone us. (This paragraph is well written) In short, it's good to be satisfied or not satisfied. Its advantages can only be brought into play if there is a certain foundation. We should plan our life reasonably between satisfaction and dissatisfaction.
