Preface
1. Actively learn, strive to improve, and walk with the development of society
The longer you have worked in the workplace, the easier it is to form a stereotyped mindset. This may be the effect of mental rigidity. This habitual thinking is one of the major reasons for reducing the living space of middle-aged people.
With the emergence of new industries and new technologies, if you want to not be eliminated by society, you must have iterative thinking, actively break through the inertia of thinking, accept new knowledge, and keep yourself away from the title of "old fritters" in the workplace. This effort will only make your path wider and wider.
2. Become into the circle and establish network resources
If you want to improve yourself, you must force yourself to join the circle you want to enter, so that you can meet different people and build the network resources you want.
3. Improve self-discipline and have health
Health is the capital of the revolution. Many successful people understand the importance of health, so no matter how busy they are, they will never forget fitness. Ma Yun played Tai Chi every day and Wang Shi jogged every day.
Although you are now 35 years old or are approaching 35 years old, as long as you don’t let yourself go and stick to these three things, I believe you will not encounter the so-called mid-life crisis, let alone find a job.

Learn to share
In the current era of information sharing, many resources can be found on the Internet, depending on whether you are willing to find or find the right method.
Many friends are not without information, most of them have dozens or hundreds of Gs, but they are messy and they don’t know how to look from where to look, or even forget after they look.
If you feel that the information you find on the Internet is very messy and out of structure, I will share a set of it with you. It is more systematic, and I usually study it myself.
The latest tens of thousands of pages of real interview questions in 2020
Seven module learning materials: such as NDK module development, Android framework architecture...
Only systematic and directional learning can quickly improve their skills within a period of time.
This system study notes is adapted to the crowd:
First, the learning knowledge is relatively fragmented, and there is no reasonable learning route and advanced direction.
Secondly, after several years of development, I don’t know how to go further, and I’m confused.
Third, at the right age, I don’t know how to develop, transform management, or strengthen technical research. If you need it, I happen to have why, don’t come to receive it! Maybe it can change your current state!
