What is mental weakness? What kind of person is prone to mental weakness?

Strength and weakness may be hereditary to an extent; some people are naturally strong, others are naturally weak. But the more important factors are environment, educational background, and habitual dispositions. Relatively speaking, a person who is born into a wealthy family and educated in a prestigious institution is more likely to be mentally weak. As a result of this weakness, the person is fussy and difficult to work with. When this disposition develops into a habit, it becomes increasingly serious, to a point where all things are repulsive and unsatisfactory. In the end, such a person will find no meaning or happiness in life, and may even take drastic measures.
