Mental soundness is a very important issue for any nation, society, family, or individual. A person can be considered mentally sound if they are satisfied with their own abilities, can adapt to changing situations and extreme work pressure, and can support their family in critical times. Conversely, a person who fails to adapt to critical situations, struggles under extreme work pressure, and cannot support their family may be considered mentally ill. A mentally healthy person maintains positive thoughts, approaches challenges with optimism, and seeks lessons even in negative situations.

However, in many male-dominated societies, women are often suppressed and dominated. What is truly desirable for women in society? According to statistics from 2019, on average, 13 women are raped every day, totaling 4,745 women and girls per year. This is a shameful reality, reflecting our failure to ensure safety and security for women. If women are not allowed to develop their inherent and external qualities, skills, and working abilities, the development of our country and society will remain incomplete.
