Struggle will beautify your life. When you deeply understand life and deeply purify your mind, there is an indispensable spiritual food, and that is the wonderful word "struggle". In life, we should always correctly treat the right and wrong transformation and failure in the journey of life. Therefore, as the fruit of harvest, don't let the years pass, look back at your achievements from time to time, we just keep looking forward. The struggle is endless. Lofty ideals and firm will can only be formed through struggle. Good wishes and sweet dreams can only be displayed in the charm of pursuit and struggle. Struggle is the art of strength. Without struggle, how can the tree of life be evergreen? A philosopher once said such a thing; "There are two tragedies in life, one is not getting what you want most in your life, and the other is getting what you want most in your life." The greatest meaning and value of life is happiness and happiness. Let's create a better life together. If a person has no goal, then he will not succeed and a good life will leave him. Struggle is a solid step of will. The footprints of all successful people are full of hard work and sweat. No matter how big your faith is, your will will will be strong. Without diligent practical actions, everything will be empty. Struggle is a long-term hard work. Struggle has become our young people's good moral character and habit of seeking knowledge. People who are fickle, hesitant and unwilling to sweat will never taste the sweetness of diligence. We may have the same name. What's your last name? Humans evolved from animals. Therefore, when people exist as human beings, they are not pure natural existence, but dual existence, both natural existence and social racial existence. The existence of human beings as a race is obviously fundamentally different from pure natural objects, but we must never forget that human ancestors started from animals and originated from animals. Some animal genes will accompany human life. People and animals are inextricably linked and confused, with the characteristics of * * * *. The evolution of human beings from animals to humans has gone through a very long and difficult time, and the transition from barbarians to civilized people and real people will also go through a long and painful evolutionary process of countless generations. Therefore, people-oriented should only be based on realistic people, not just people and people. We should not only see the differences between them, but also see their similarities; We should not only see that we humans have strong rationality and consciousness, but also see that animals are often crazy and dumbfounded. Marx pointed out: "The first premise of any human history is undoubtedly the existence of living individuals. Therefore, the first concrete fact to be determined is the physical organization of these individuals. And their relationship with nature, which is limited by physical organization. -any historical record should start from these natural foundations and the changes that have taken place in the historical process due to human activities. " [1](P24) Living individual organism is the realistic carrier of all people's material production and spiritual production activities. This is the first premise of any human history. Modern biological science research has fully confirmed that most characteristics of human beings (such as height, weight, intelligence, etc. ) and behavior is controlled by many different human genes and can be inherited. Environmental factors will have a strong influence on gene expression, and the environment can amplify or hinder the role of genes. However, the environment cannot replace or exclude the role of genes. Animal tissues without human genes can't become human no matter how they live in human environment. After the long-term efforts of scientists, human beings have finally opened their own book of life: human beings have 23 pairs of chromosomes, each pair of chromosomes contains thousands of genes, and each gene is composed of complex bases in different permutations and combinations. The human genome has a sequence of 3 billion nucleotides-although it may take hundreds or thousands of years for humans to truly understand this book, we have already learned some general concepts, such as the genetic differences between humans and chimpanzees, the genetic differences between races, the genetic emergence of diseases, and even behaviors such as obesity and suicide. Most of the secrets of human character are buried in genes. Of course, the innate influence of human genes is intertwined with the acquired "cultural genes" of human beings. The problems exposed by the recent murder of four students in Ma Jiajue are obviously not only general socio-economic and educational problems, but also reflect that we need to strengthen the research on human life, the role of human genes, and the research and targeted prevention and treatment of personality disorders caused by genetic defects. Only in this way can we adhere to humanism. What is human nature? This is a sensitive topic that has been controversial for a long time. One view is to separate the two: human nature refers to human animal instinct, while human nature refers to something that people should transcend animal nature. Another view regards the two as exactly the same thing: humanity is humanity. There is only an abstract understanding of human nature or human nature (such as human nature is good and inherent vice); There is only a specific understanding of human nature and humanity (for example, only emphasizing human class and social history, etc.). None of the above points of view distinguishes the proper connection and difference between the two. The uniqueness of Marx lies in that he insists on looking at the relationship between human nature and human nature from a connected, developing and dialectical point of view, and regards them as dialectical unity with both connections and differences. Strictly speaking, Marx did not give a clear definition of human nature or human nature, but the meaning between the lines of these two basic concepts is still very clear. Especially in Marx's original works, these two concepts are often used in different contexts, such as "conforming to human nature", "being suitable for human nature" and "owning human nature" and "realizing my human nature", so as to clearly reveal the internal relations and differences between them: the relationship between human nature and human nature is as follows. The difference is that human nature is a generalization and abstraction of the class characteristics of human objective existence, that is, basic * * *. Human nature mainly refers to the individual's self-knowledge and personality development, and it is an analysis and induction of the differences of human personality and the essential differences of social contact, social communication and social relations between people. Generally speaking, it refers to the basic attributes that distinguish human beings from other animals. Marx's view of human nature mainly includes three basic points: (1) the fundamental motivation and internal intention of human life activities, and the self-realization desire of survival and development. (2) The essence of human life activities is free and conscious movement. (3) The way of human life activities is to form certain social relations. These three are interrelated and complementary. Some people think it's human sociality, while others think it's people's free and conscious activities. This paper holds that according to Marx's humanistic thought, the fundamental motivation and intention of human life activities-the desire for self-realization should be the origin of human nature and the original difference between human and animals. The so-called desire for self-realization refers to the innate desire potential of human beings. Broadly speaking, it includes the lowest level of self-interest desire for food, clothing, housing and transportation safety, the middle level of emotion, socialization and respect, and the high level of self-worth desire to show self-ability and improve self-personality. This desire for self-realization objectively exists in the depths of people's hearts, and it regularly increases and develops with people's life cycle and external stimuli. Although everyone's desire value is different, the potential desire for self-realization is the same. When analyzing human nature, Marx pointed out that "their needs are their nature". "In order to be able to' create history', people must be able to live. First of all, they need things such as food, clothing, housing and transportation. Therefore, the first historical activity is to produce materials that meet these needs, that is, to produce material life itself. " "When people start to produce the necessary means of subsistence (this step is made by. They began to distinguish themselves from animals. " "The first need that has been met, the activities that have been met and the tools obtained to meet the needs have caused new needs". [1](P32, P25, P35) New needs will produce new historical activities of self-realization. It has been going on. In his analysis, Marx put quotation marks on the word "creating history" to show that "creating history" here is not subjective and conscious, but refers to the potential, subconscious and potential desire of human beings to "create history" to show their self-strength (realize themselves) before the first historical activity, and this potential is determined by their body organization. Driven by the innate desire to create history and realize oneself, human beings have produced free and conscious social production and other practical activities. Productive labor has further created human beings and human society, and promoted the continuous evolution and multidimensional development of human beings. The tenacious and extraordinary desire for self-realization is the objective basis and internal motivation for human beings to create social history freely and consciously. People's free and conscious activities and sociality are derived from this. Judging from the innate conditions of our ancestors' "body tissues", apes are not as fast as horses, as powerful as cattle, as fierce as tigers and wolves, and as clever as chimpanzees. But why did man finally become the king of the universe and the soul of all things? Why can humans continue to evolve and develop while other animals remain at the primitive level? The fundamental reason is that human beings have multi-level, multi-dimensional, infinite growth and insatiable self-realization drive and desire, while the desire of ordinary animals is low-level, one-dimensional and less changeable, so it is easy to meet the instinctive needs such as "food and clothing" and nothing else. Modern scientific research has found that people's desire for self-realization is embedded in people's genes, just like people's potential physical strength, intelligence and other objective existence, it is independent of people's will and greatly affects people's development in many aspects. In the laboratories of Rockefeller University and Yale University, neurogeneticists have isolated a gene called VIRLI, which is closely related to human desires. Stimulated by external pheromones, this VIRLI desire gene makes human beings have positive self-awareness and reaction, and produce specific goals and desires. Then the desire will be transformed into self-fulfilling action to achieve the greatest satisfaction of self-desire. Generally, animals lack this special desire gene, so they can only have low-level and one-dimensional desires forever, and cannot fully evolve and develop. Internal cause is the basis of change, while external cause is the condition of change, and internal cause works through external cause. Therefore, human beings, and only human beings, will have lofty ideals and social plans and will constantly refresh and create their own history. The so-called self-realization, of course, cannot be separated from oneself. As Marx said, in any case, individuals always "start from themselves". "For an individual, the starting point is always oneself" "If anyone doesn't do things for his own needs and organs at the same time, he can't do anything" [2] (P86, P286) Engels also thought: "Before we can do something for something, we must first turn it into our own thing, a service for ourselves" [3]. The founders of Marxism believe that "starting from oneself" and "taking advantage of oneself" are the most humane and normal internal motivation and vitality source for human activities. Today's reform, opening up and institutional innovation are also aimed at establishing an internal mechanism and mobilizing all positive factors (desire for self-realization). Does this mean that human beings are doomed to live in the shadow of selfishness and extreme individualism? That's not true. This is life!
