Your personality traits are rather stable, once they are formed. Slight changes can be measured.
Personality traits are hereditary and therefore innate. They change their orientation slightly in childhood and are then largely stable over time. Mental illness can change your personality for this time.
it is important to know that there are no good or bad traits. Every person is unique and has its strengths and weaknesses. Every trait, whether high or low, has its advantages and disadvantages.
