Of the three, the one that must not be contaminated is probably pessimism. There is a report in the newspaper that a famous college student committed suicide. Maybe they are too pessimistic about their future! Although I went to a key university envied by others ten years later, the social competition was too fierce, so I chose to commit suicide. In fact, flowers bloom and fall, the moon is full and people are round, and life is not perfect. It is impossible for college students who commit suicide not to understand these truths. If you have difficulties, you have to face them. If you have no difficulty, of course, don't worry. Pessimism makes those social darlings give up their lives and a life that could have been wonderful, which is really sighing.
In contrast, optimism is another realm of life. Full of confidence in everything, energetic, and go all out to complete the set goals. There are thorns on the way forward, but there is no fear. Even if you are stabbed, you will not be discouraged. These people may not have achieved much, but they have saved a lot of unnecessary trouble. A happy life is happy. An optimistic person faces the world with a smile and finds that the world has been smiling at himself.
However, the highest state of life should be philosophical. A philosophical person can see the world from a height that ordinary people can't see. Fan Zhongyan's "don't be happy with things, don't be sad for yourself" is the best summary of a philosophical person. Regardless of the gains and losses of honor and disgrace, you can always have a calm mood and face it calmly. People who do not have a thorough understanding of life cannot have a philosophical attitude. Those who remain calm after being hit are often impressive. Su Dongpo is a great writer. He is frustrated in officialdom, but his open-minded mind and bold style of ci make him occupy an important position in the history of China. Tao Yuanming, who lives in seclusion in the countryside, naturally wants to escape from the dark society. However, after he resigned, he began to manage Taoyuan attentively, drawing a clear line with utilitarian and vulgar things. It can be seen that he is aware of political corruption, and he is incompatible with it and unable to change it. He simply jumped out of the mud, found a quiet place to live in seclusion, get close to and enjoy nature, and was barely a philosophical person!
Stay away from pessimism, people will be less sad; Learn to be optimistic and you will be happier; Learn philosophy and you will be calmer and wiser. Choose a good attitude and get a successful life.
