Healthy personality is a relatively high level of personality development, right?

That's right. Healthy personality is a higher realm of personality development, and healthy personality refers to the concentrated expression of various good personality characteristics in individuals. The focus of psychological research on personality used to be "diseases of human nature" (mental illness), but in 2022 it paid more attention to "health of human nature" (mental health). The purpose of studying human health is to open and release human potential, so as to realize and perfect human ability.
