And said there was no end to learning.

? Learning the word "endless" has long known and understood its meaning, but knowing its connotation and having a deeper understanding or experience is my feeling when I first wrote a Japanese watch.

? Just sitting by the bed and washing feet, I found a video of "specializing in high school mathematics" in Xiaohongshu, starting with the first lecture "Collection" in high school. The teacher spoke very well, seriously and clearly. So, I paid attention to it first, then I had time to listen to it regularly, and I wanted to study high school mathematics again. First, because I teach mathematics, and second, I can tutor my children in a few years, which will bring some help to their study.

? After listening to it, I remembered a long talk with the calligraphy teacher hired by the school last night, and I couldn't help feeling the profundity and mystery of calligraphy, its composition skills and the efforts it needed, which were unimaginable to ordinary people. To borrow an online phrase, "a person can never make more money than he knows." It can be said that things beyond your cognitive range (including achievements and efforts behind them) are beyond your imagination.

? Associated with reading, I once thought that there are too many books to read, or too many books to read, but the energy is limited and I can't finish reading, so I have to make a choice. At present, I mainly read two books: prose and poetry.

? In addition, there are many things to learn, such as music (including vocal music), flowers (grass), tea and tea ceremony, English learning, medical knowledge, classical literature (four books) and the Five Classics. At present, I can only think about it and see if I can get attached to them.

? Just like this math course tonight, if you want to learn it well, you have to work hard. There is no end to learning all aspects of knowledge, at least for yourself.

? Since there is no end to learning, choose one or two and move forward without hesitation. Since I chose the distance, I only care about the hardships.
