In the 21st century, fitness and learning have become hot topics.

Entering the 21st century, fitness and learning have become hot topics. But the degree of heat is different. Fitness is a real "hot", which can be reflected in three aspects: First, fitness education books marked by " on the health express " launched by experts have been selling well. Secondly, regardless of the size of the city, the gym has become a place for many working-class people to check in for fitness. Thirdly, from towns to villages, wherever you can exercise, you can do it morning and evening, walk your dog, walk your dog, walk, jog, and jump in the square. There are people who dance, practice Tai Chi, , etc. I have never seen people pay so much attention to and devote themselves to fitness. However, people's emphasis on and investment in learning, which is "recharging", pales in comparison: although you can often see busy scenes of people in many bookstores, they are more common during holidays, and most of them are adults leading children to search for books ( Of course, nowadays people can buy books online, not necessarily in physical bookstores). If you look at trains, buses, and park seats, most adults hold mobile phones in their hands, and paper books are rare.

It’s not that you don’t learn by looking at your mobile phone, but the knowledge you get from your mobile phone is mostly fragmented and not comprehensive or systematic. Therefore, if a person only stays with his mobile phone for eight hours without separation, strictly speaking, it cannot be regarded as real learning. To study in the true sense, you need to deal more with paper books (note that there are a large number of books that do not have electronic versions. In this case, you can only look for paper books), read more and engage in your own work. Read more professional books that are relevant to your work, and read more books that can reflect the rapid development of human society and the rapid changes in science and technology, so as to broaden your life horizons and enrich your brain.

I can’t tell from which year or month, a joke about “What you know and what you don’t know in college” that resembles a roundabout word spread like wildfire on the Internet: “When I was a freshman, I didn’t know that I didn’t know, and when I was a sophomore, I knew that I didn’t know. "You know, you don't know what you know when you are a junior, but you know what you know when you are a senior." It means that when I was a freshman, I was still like a little kid, blindly optimistic, thinking I knew everything, but actually I didn't know what I didn't know. There are too many, so there is no respect for knowledge and learning. When I was a sophomore in college, as my studies progressed, I looked around me and saw that people who were far better than me were still flying hard. I knew that human knowledge was vast, and the knowledge I had learned was just a drop in the bucket. Realizing that there was too much knowledge that I did not understand, I initially developed an "empty cup mentality" and determined to continuously enrich my knowledge and knowledge. Entering the junior year, with the continuous expansion and growth of professional knowledge, my "heart" is focused on learning. Slowly, my knowledge becomes thicker and deeper. I think I know everything when I don't understand it; I know that I don't know everything. Know: Begin to have a sense of awe and be able to welcome new cognitions; Know that you know: You have a certain depth of cognition, but you still have your own blind spots; Don’t know that you know: In the realm of , great wisdom is as stupid as , always maintain an empty cup mentality. Based on this perspective, it makes sense that most people in the world belong to the middle two parts of the "football" of the four cognitive levels. The wise people who are at the cognitive level of "don't know what they know" are like fools. Their enterprising consciousness and fighting spirit of always maintaining the " empty cup mentality" on the way to seek knowledge are the hope of the Chinese nation and are always worthy of our praise and imitation. The most disgusting, despising and despising people are those people who "don't know what they don't know". They read little, but feel that they know everything. If this kind of person doesn't wake up quickly and catch up, one day his work may be done for him by others, and his rewards may be collected and enjoyed by others.

Needless to say, the theory that "reading is useless" still has a market in some corners and among certain groups of people.

If you tell them that "recharging" can nourish life; master more skills and increase more income by reading and learning professional books, reference books or financial management books, and with knowledge, you can have more choices in life. The principles and prospects of doing more meaningful, valuable, and time-consuming work instead of being forced to make a living; talking about those inspirational examples who rely on "knowledge to change their destiny", they will immediately point out that someone around them does not study. After making a lot of money, a certain college graduate can't find a decent job and can only make a small amount of money to support his family. In doing so, they obviously ignored the basic fact that "the probability of becoming a talented person without studying is lower than that of a person who reads" and "not studying will lead to a lifetime of humility and low status."

Nowadays, competition in all walks of life is fierce, but there are many outlets and many opportunities. However, the past era of relying on muscle contraction to determine strength is gone forever. If a person wants to become a talented person who is useful to the family, society and country, he must continue to improve his strength and confidence through persistent learning, so that his "irreplaceability" is stronger than others. Maybe we will still be a small person after struggling all our lives, but life will always give us more choices. At least, our life will not be too bad.

friends! Please don’t choose comfort when you can endure the most hardships. No one will succeed easily: don’t forget to strengthen your brain when exercising, and don’t forget to charge yourself when charging your mobile phone.
