Psychological defense war
In biology, the two substances secreted in the human body, dopamine and endorphins, are widely considered to be the main factors that trigger feelings of euphoria. 
Dopamine is a catecholamine neurotransmitter synthesized in the nervous system. It has an important impact on the control of movement, emotional responses, cognitive function, and regulation of the endocrine system. The release of dopamine is often associated with rewards and feelings of pleasure, such as when enjoying a meal, achieving an achievement, or experiencing a pleasurable activity, where dopamine levels rise, triggering a positive, euphoric feeling. Endorphins, on the other hand, are peptides with a variety of biological activities, which are mainly synthesized in the hypothalamus and pituitary gland of the human body. Endorphins are not only involved in the regulation of pain perception, but also play a role in mood, stress response, and immune system function. Unlike dopamine, the release of endorphins is often associated with stress and pain. For example, when doing aerobic exercise or experiencing some form of physical stress, endorphins levels rise, which not only helps to reduce the feeling of pain, but also creates a deep sense of relaxation and satisfaction, sometimes referred to as "runner's pleasure." Today, smartphones are like our other hand, inseparable from us. The short ** on the mobile phone is even more popular with the public. The word "brush" vividly depicts the continuous, fast, and slightly addictive state of people's **short**. The beauty of short** is that it can precisely stimulate dopamine secretion in our brain. This substance, known as the "happy hormone", not only causes us to experience excitement and pleasure, but also forms a positive feedback mechanism that drives us to constantly seek out more stimuli. Every swipe, every refresh, is like opening a small box full of surprises, looking forward to the next ** will be more exciting. It's not just short**, many things in life can trigger the secretion of dopamine. Food, desserts, milk tea, and even intimate interactions with lovers can make us feel this surge of pleasure. However, when this desire for pleasure is excessively amplified, it can lead to addictive behavior. The word "addiction" always carries a sense of extreme dependence and inextricability. In order to get the pleasure of that moment, people tend to lose their minds and do all kinds of unbelievable behaviors. Whether the child is addicted to mobile phones, games, or ** for food and love at all costs, behind it is the invisible hand of dopamine that is manipulating. What's even more terrifying is that when we come out of the illusory world of dopamine, we often feel an indescribable sense of emptiness, loss, and frustration. We will realize that we have wasted a lot of time on these things without being truly satisfied and growing. This feeling makes people instantly languish, and a voice will continue to echo in the depths of the heart: "Alas, this time has been wasted again!"."Since dopamine in the human body cannot be obtained in large quantities for a short period of time, is there a substance in the human body that can get high, not addictive, and give people a sense of accomplishment?The answer is yes, and that's endorphins. Endorphins, on the other hand, are a more lasting and far-reaching source of happiness. It's a compensatory hormone that is quietly released after we experience challenges and put in the effort. Endorphins not only give us the satisfaction of accomplishments, but also give us a deep sense of pride and self-affirmation. It is our faithful companion in the long journey of life, witnessing our growth, hard work, and perseverance. Imagine that at work, you stay up late planning and organizing an event, and in the end you get a complete success. The sense of accomplishment from the inside out, as if a warm current is surging through your heart, is where the magic of endorphins lies. In learning, when you persevere in reading a heavy book, the joy of returning home and the pride of self-transcendence are also the gifts given to you by endorphins. In life, whether it's running a 10-kilometer run or overcoming a challenge, the pride and satisfaction that rises from the bottom of your heart are all endorphins cheering you on. Of course, choosing to pursue endorphins is not an easy task. Dopamine is everywhere, it's like a tempting candy that makes us irresistible. However, it is only when we learn to resist this immediate ** and turn to the arms of endorphins that we can truly taste the sweetness and richness of life. Embracing endorphins, we need to develop the qualities of self-discipline and persistence. Set clear goals and put in the hard work and sweat for them. We may encounter difficulties and setbacks along the way, but it is these challenges that shape our will and character. When we finally overcome obstacles and achieve our goals, that sense of joy and accomplishment from the inside out will be the best reward for us.
