foreword
Recently, Zhang Chaoyang, the founder of Sohu, and Wang Shi, the founder of Vanke Group, had a live chat.
Zhang Chaoyang said to young people that if you want to make contributions and leave traces, time is very precious. "Don't look at you young, but time will pass quickly, so hurry up. Don't stay up late, go to bed early and get up early, don't sleep late, okay?"
Zhang Chaoyang also suggested that you must get up earlier, getting up at 6 o'clock every morning.
As a programmer, I don't really agree with this statement.
Although 2023 is still in the cold winter of computers, the environment for programmers is not good, and the employment situation is relatively stressful.
It can be rolled, but not like this.
The high school life of getting up at 6 o'clock every day, you can't go back
High school is the most memorable period in everyone's growth. It is youthful and ignorant, youthful and innocent.
The classroom carrying dreams, the sweaty basketball court, and the canteen packed with people after class. . . There is also a once-in-a-lifetime 100-day swearing-in meeting.
High school is the most youthful age.
But let you "get up at 6 o'clock every day" like high school now, and devote yourself to learning as much as you can. How many people can do it.
After the college entrance examination, there is a book tearing contest to vent all the "dissatisfaction" in the past three years
volume is necessary
There are many industries involved in this, and I will take programmers as an example.
Since the outbreak of online and offline training courses a few years ago, this day will come sooner or later. Now it is obvious that the market environment is oversupply. At this time, if you don't change careers and don't roll, then what advantage can you show.
Educational advantage, please, isn’t this something you rolled out in high school?
You now need people who are better than you at the same level, so that your own value can be noticed.
I still remember that if you knew calculus in college, you were better than your peers.
Now most people know calculus, but if you don’t, then you are weak.
how to roll
When you recognize your own shortcomings, it has been proved that many people surpass you . ,
And we are not that high school age now, with so much energy and so much time. If you just roll with no direction, then you will never surpass those who roll at the same time.
So what should we do?
The great man said well, one must seek truth from facts. You have to plan according to your own situation. Now we don't have so much time to learn all aspects of knowledge, and we don't have the energy to get up at 6 o'clock.
It's better to give up some things, focus on a certain popular point, use limited time and energy to learn, and learn it well.
how do i do it
Because I am an Android programmer, I must pay attention to the learning of the Framework. When companies are screening Android programmers, they are more and more interested in a programmer's understanding and thinking about the bottom layer of Android. And if you want to advance, Framework learning is essential.
Framework also includes a lot of things, and I am also picking up the learning.
Learning should focus on one point, after all, energy is a limited thing.
epilogue
It's not that what Zhang Chaoyang said was bad, it's just that young people don't have so much time and energy now.
This is just my personal opinion.
In today's society, rolls must be rolled. Programmers need more volume. If you are an Android developer, share a Framework learning material and roll it up.

Android Framework study guide, family bucket learning materials (including Framework development secrets, kernel analysis and high-frequency interview questions)
Framework is the application framework layer, which is a key component of the Android architecture. It provides us with a lot of APIs for developing applications, so that developers can start the development of APPs by simply calling the APIs, without having to understand the complex bottom layer of the Android system in detail. Knowledge.
In order to help you understand the function and structure of the Framework in the entire Android architecture, systematically learn and master the Android framework, here we specially collaborated with Ali P7 architects and Google technical teams to organize a learning material for the Android framework family bucket.
Summary: "Android Framework Development Secret"; Summary of Android Framework high-frequency interview questions; Android Framework refined kernel analysis; Android 11.0 latest Framework analysis.
Content features: clear organization, including graphic representation, which is easier to understand.
