"Review the past and learn new things, and you can be a teacher." You can read the classics extensively, review what you have learned, and then gain new insights from them. You can also try to absorb new knowledge to achieve mastery and continue to do so. Only by doing this can we be called a teacher. As long as you review the old knowledge you have learned, you will have new experiences and discoveries. You will gain more, you will know more than others, you will learn more than others, so that you can become someone else's teacher in some way.

In life, everything, every sentence has many aspects. Different people have different understandings. Maybe you can only understand one of them for a while, but when you have experienced more and learned more, you may have a different understanding and experience when you go to see it again. Life is so many sides. When you don't understand a word, do you choose to abandon or ponder? When you delve into it many times, you will have a different experience.

When we are busy with a stage of things, we take advantage of the temporary busy time and look back at the dribs and drabs, only to find that we can't be slaves to work. Learn to think and summarize, and make your work full of persistence and growth.
