Meet the challenge and strive to grow.

　　Life is a process of continuous growth and understanding, and our growth is not achieved overnight, but requires many transformations and turning points. The three stages described in this passage represent people's cognition and understanding of themselves and the world in different periods, which are indispensable experiences in our growth process. When we were children, we often felt that we were the center of the world and everything revolved around ourselves. However, as we grow up and come into contact with a wider world and people, we gradually realize that we are not the center of the universe, and there are countless lives like us in this world. This is a cruel reality, but it is also the beginning of our growth. We began to learn to care about others, to get along with others, and to find our place in this world. When we enter adolescence and start chasing our dreams and goals, we will find that no matter how hard we try, there are still some things we can't do. We may encounter setbacks and failures, but we also learn from them to struggle and persist. We are beginning to understand that success is not achieved overnight, and it requires hard work and sweat, as well as enough patience and perseverance.

　　However, when we enter middle age, we will find that even though we have tried our best, some things still cannot be changed. We may encounter great changes in our lives, such as losing relatives or friends, or encountering setbacks and failures in our careers. These things make us feel powerless, but we also begin to understand that the essence of life is impermanence and change. We began to learn to accept these changes, and at the same time began to cherish the people and things around us more. Although we have experienced many growth and turning points, our journey of life continues. We will continue to face unknown challenges and difficulties, but we also have more experience and courage to face them. We begin to understand that the meaning of life lies not in the pursuit of perfection and invulnerability, but in bravely facing our own shortcomings and defects, and constantly striving and growing. The three stages described in this passage are indispensable experiences in our lives. They let us learn how to face ourselves and the world, how to seize opportunities and meet challenges, and how to accept impermanence and keep courage. I hope that through this passage, you can get inspiration from it, meet challenges, strive to grow, and finally achieve your desired goals.
