Buddhist teachers have repeatedly pointed out the importance of being mentally strong. People who are mentally weak are more likely to suffer.
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.
