How to be an inner powerful person?

In addition to ideological independence, life independence and economic independence are also the foundation of a strong heart. A man who relies everywhere is insecure and can never be strong in heart. A strong heart needs to have enough confidence and sense of security for oneself, that is, no one can believe that he can lead a good life alone. Some people do not dare to offend.
