Happy to share what I learned in 2018 on the Nuggets.
Most of this article is non-technical.
1. The difference between knowledge and skills
In 2018, I bought a course, 5-Minute Business School. After hearing one of these lectures, I was inspired. It affected me for a whole year.
The idea is simple: make a distinction between knowledge and skill. Knowledge can be learned, but skills can only be learned. Don’t treat skills as knowledge.
The paper come zhongjue shallow, and must know this to practice.
Although this phrase often appears in my writing. But after listening to that talk, it still seemed to hit me head on and make me think deeply.
Usually very like reading, most of the time used in reading, technical and non-technical I read.
Before, I always thought reading was a very good way to learn. That day I realized that all I had been doing was learning knowledge rather than skills. What I really need is some useful skills, not book knowledge. Self-control, for example, is a skill that requires constant practice. I just read books, several of them, and all I learned was information on how to practice steps effectively.
Do you say JS is knowledge?
It’s a skill, even if you know everything about it, such as this’s various directions, closures and scopes, prototypes and inheritance. And when doing a project, solve a problem but have no idea basically, everything is also in vain.
I wrote the JS Mini-Book of Regex and thought I knew enough about regex. In retrospect, regular play is a skill that requires constant practice. When you face a problem, you can solve it calmly.
Last month I found Codewars and started doing regular problems. Even when I was thinking hard, I felt happy. After submitting the answer, I looked at what other clever people were doing and thought I had learned it again.
2. Shoot arrows to draw targets
Skills to master, knowledge is also to learn. But you have to put it to use.
How do you use knowledge?
The quickest way to apply knowledge is to teach it to others.
One day I saw a great video and wanted to share it on my moments. Later, I thought why not share it with Zhihu? So that more people can see it. Suddenly I realized: isn’t zhihu the place to teach knowledge to others?
Although ZHIhu has been used in the past, it rarely answers questions.
That day I realized the following:
When someone invites you to answer a specific question, you may not be able to do so because you don’t have enough knowledge or insight.
But what about the reverse? What if you learn a knowledge, and then go to zhihu to find the corresponding question, answer?
Hit it where you want it. You can’t do that. But I’m sure you can do that.
Later I gave it a name and called reverse thinking archery target drawing. Shoot the arrow first and then draw the target.
You have to give a name to a good thing, or you won’t remember it.
I got several people to organize a group and applied what I learned from 5 Minutes Business School on Zhihu. Even if later we do not insist, I think, as long as everyone answered their own knowledge, it is still impressive. At least I did.
3. Relationship perspective
I used to say to myself, try to focus on things, not people.
After listening to “Chen Haixian’s Self-development Psychology”, I suddenly realized that there is a relational perspective. It’s the reverse logic, to the person, not the thing.
I used to see other people argue red in the face about some trivial things, and I really don’t think so. Now it turns out that it’s not the things they both value, it’s their relationship that’s having trouble getting into involuntary arguments.
When the relationship is good, nothing is called a problem. When the relationship goes wrong, the chicken feathers become a big deal. In the future, when you come across something, don’t just respond to it, respond to the relationship with it.
This point, possibly, have an object of the classmate should understand more profound.
4. Thought experiment
I don’t like watching movies in recent years, because SUBCONSCIOUSLY I think movies are a waste of time. If I do, I fast forward at every turn.
Later, when I heard someone interpret the Three-Body Problem from the Angle of thought experiment, I realized: originally, science fiction is doing thought experiment!
A thought experiment means you don’t have to do it in reality, you just do it in your head. More convenient! Of course, most are not convenient to do in reality.
Snake fight seven inches, you say a planet civilization seven inches is what? The answer given in the Three-Body Problem is fundamental physics.
If a woman is beautiful, she will get more or less preferential treatment in life. Do you think it’s unfair to a girl who looks ordinary? Imagine what would happen if the country imposed a tax on beautiful women? It’s just a thought experiment. It doesn’t need to be applied in real life. What exactly is going to happen? There’s an episode of The World’s Wonders about it.
The knowledge that science fiction is a thought experiment makes me feel that watching movies is no longer a waste of time. A while ago, “The Tomato Man” was very popular. While watching it, I immediately realized that it was a thought experiment: Given a billion dollars, what would you do with it?
5. Mindfulness
This is the word I learned the most in 2018. It helped me quit smoking.
I think mindfulness and flow are opposite concepts.
Mindfulness requires you to be aware, to be aware of yourself, to observe yourself. Flow, on the other hand, requires you to forget yourself and do things to get lost in yourself.
Here’s my quit. I didn’t know the concept of mindfulness, and I didn’t know mindfulness therapy.
One day in the middle of the night, woke up to look for smoke, found that smoke out. After hours of painful endurance, it finally dawned.
As I got out of bed and went downstairs to buy some cigarettes, I realized that it’s really fun to observe yourself in pain. Thinking of this, I found myself laughing. Unexpectedly at that moment, I started to quit smoking.
A month later, I wrote in my moments:
Here’s how I quit smoking: You need to recognize the existence of the three selves. The me who desires to smoke, the me who is observing me who desires to smoke, and the me who is aware of both.
It turned out that this is the concept of mindfulness, awareness of self.
6. Technology
That’s five important things I learned in 2018. In the following section, I am prepared to give a general overview of the year’s personal gains in front-end technology.
In May, a single project finally came online. The technologies used are REACT and BABYLONJS. The latter is the WebGL framework. During this period, I also learned about the native WebGL technology completely. Because the product needs to be operated on a touch screen, a gesture library supporting multi-finger recognition is implemented.
Subsequently, several VUE projects, large and small, began. Well, finally playing VUE.
Two of the projects to achieve language communication, early learning WebRTC technology. I mean, I found a frame behind it, but it didn’t work. However, also feeling ah! A few years ago, I was in charge of a voice communication project at my previous company, and I used Internet Explorer’s ActiveX controls at that time. Unexpectedly, WebRTC has developed so fast in recent years.
An interesting thing happened at the end of the year, a colleague asked me how to do a project that uses the Discrete Fourier transform. Although I learn math, but the knowledge back to the teacher. Yeah, it took a couple of hours. Look for data, watch video finally solved, be so many years, the first time to find their math or not in vain.
Over the course of this year, I’ve been asked, “Why don’t you learn artificial intelligence?”
Actually, I did a little bit of preparation. I spent some time learning Python last year. The so-called learning, that is to follow a few demo, familiar with the next grammar. Get ready to practice in CodeWars this year.
Another whim also bought a set of “advanced mathematics exercises”, ready to pick up high number. Ah, only insist to differential that chapter, ashamed!!
7. Don’t have too many goals for the New Year
A while ago, friends said he didn’t accomplish many of his goals for the beginning of the year. I think I am, too. You can’t really do a lot of decent things a year. One or two goals a year are good enough.
My goal this year is only one, “Fan Deng Reading Club” that 200 episodes, listen to each episode carefully, do not waste the impulse to buy members.
In this paper, to the end.
Thank you for seeing this.
Welcome back to an important Lesson from 2019.
