How to enhance mental strength, in my opinion, there are three main points to enhance mental strength.
First, reasonable assumptions about the environment
When adapting to a new environment, it is best to assume that "the world is not perfect" and "human nature is positive" at the same time.
Second, invest resources to build your core capabilities
What are the core strategies for a person's growth? There are two main points.
First, continuously invest resources in core capabilities, and second, find resources to make up for the key shortcomings that restrict the development of core capabilities.
The former is offense and the latter is defensive. To reach farther away, you must be both offensive and defensive.
Third, when encountering problems, look inward for the cause
The environment is bound to change, and you are bound to encounter different challenges.
The world changes, and it will definitely expose your problems continuously. The more serious the problem, the better the opportunity to exercise your mental strength. The most important attitude to the problem is: "Look inward for the cause".
