The pain and joy of learning the sea is how hard it is to sail in the vast sea, which is really more vivid and profound than the pain of learning the sea. Hanging beam overhead, stabbing with a cone, stealing light from the wall, standing in the snow at the door ... In the ocean of knowledge, suffering has been a boat since ancient times, and it is miserable. Students often say: "The student period is the most bitter stage of life. It does make sense. Smell chickens dancing in the morning and practice in the morning breeze. It is students who study in the morning light. At night, it is also the students who work hard at night. With the upgrading and further education year by year, the number of students suffering from myopia is increasing, and the degree of myopia is also increasing. How bitter it is at the same time! In a quiet classroom, the brain keeps turning with the teacher's explanation, and you can't relax by watching, listening, collecting, remembering and gathering. Scratching my head for an unsolved problem, I'm still thinking about difficulties and doubts after class, and I can't even eat or sleep ... If I don't get on the exam results, all kinds of pressures will follow ... It's really "I'm getting wider and wider, and I won't regret it, and I'm haggard for people of the same class". The suffering in learning is beyond words. However, there is more happiness in learning. When you solve a difficult problem through hard thinking and reasoning, you will be very happy when you get good grades in your study. You will feel heartfelt joy. When you use what you have learned to solve practical problems in life, you will enjoy it. When you graduate from middle school or university and use what you have learned to contribute to the construction of the motherland, you will feel infinite happiness and happiness. Learning itself contains great fun. Anyone who loves learning and studies hard will enjoy it. As the saying goes: "There is no bitterness in bitterness, and there is sweetness in sweetness. "This is the pain and joy in learning. If you want to master real knowledge and skills, you can't do it without suffering. For learning, there is joy in suffering, and there is bitterness in joy. Bitterness and joy are the unity of opposites. Knowing this, we can correctly treat the hardships in learning, not be knocked down by temporary difficulties, be confident and persistent, and strive to get "sweetness on sweetness" in learning. Only in this way can we find pleasure in suffering, ride the wind and waves in the ocean of knowledge, work hard and enjoy the infinite happiness and joy of the winner.
