1. We face serious challenges every day of our lives
Although it seems that we are all doing our own things and everything is proceeding smoothly, but in fact, it is not the case. Every one of us or ourselves is full of "crisis". The crisis mentioned here refers to your own value. Substitutability.
No matter what you do, your irreplaceability is the most important. So how to explain this? Think carefully, it's not difficult.
From a technical point of view,
your personal technical depth is very dominant in the early stages of your career . If you can achieve outstanding skills in the first 3 years and have a deeper level of attainments than your peers, then you are very Those with advantages can bring you many advantages and resources by virtue of this.
On the contrary, if you do not occupy the upper position, then the challenge you face will be much greater, which will pose a big challenge to your subsequent development space.
In terms of career skills,
if you do not expand your second survival skills on the basis of a solid technical reserve during the critical period of working for 3 to 5 years, your substitutability will be greatly reduced.
Our personal development should be changed according to the needs of the enterprise. This is called adapting to the market, or survival of the fittest. Unfortunately, there are too many people who don’t understand, or they understand too late; at this stage, the focus is on whether you have the second survival skill, whether you have taken your own route on the basis of technology, and have this skill. It is the enterprise's demand for talents at this stage.
Before stepping out of school, give yourself an advantage and
cooperate for mutual benefit. The choice of cooperation is preferred on the premise that both parties are equal.
We are often the easiest to adapt in a fixed environment, which in itself is not good for our own development. Whether you can stand out from this fixed environment determines whether you have an advantage. Compared to the workplace, in this environment you need to create both of the aforementioned advantages.
2. Technology expansion is a must
As mentioned earlier, if our skills are not deep enough, then your ability to be replaced will be great. At this time, you need your second skill to play.
Personal development over time and one's own age, the advantages and disadvantages are increasing. And most of us in this period shoulder great responsibilities. There are old people and young people. It can be said that a small sky is supported by you.
Most of this stage will be faced after 5 years of your professional career, so in this period you are no longer young Lisheng, no more worries, but whether what you master is irreplaceable and technical It is no longer the focus of the company to measure yours. What is more about you that can be tapped by the company? What do you have that "small fresh meat" cannot replace?
Like current UI engineers, low-level engineers, architects, and now popular Flutter technology. Technology may be updated at all times. If we don’t update with the pace of the times, sooner or later we will be eliminated.
3. Our strategy has been a protracted war from the beginning
We all started programming life with a "Hello World!", but few people expected this to be a game with no end in sight. In this game, if you master the rules, your level will rise. It's very fast.
