In nature, natural selection, survival of the fittest refers to a natural law in which species compete with each other and species struggle with nature, which can adapt to the choice of nature and survive.

The environment, no matter where you are, needs the coordinated adaptation of the individual and the environment. This "adaptation" not only refers to your adaptation to the environment, especially people, but also includes the understanding, cooperation and mutual assistance of people around you. First, you must be "fit" to talk about better survival. Only by adapting to one's own working environment, living environment, interpersonal environment and social environment can one make the strongest sound, give full play to one's abilities and make contributions to society.
