We all know that personality is generally pretty stable even though the recent studies have shown that personality does change over time for the better (but a slow and gradual process). One of the main reasons the personality change happens when a person chooses to do so to live a meaningful and successful life. So, if no choice is made and no action is taken, a person’s personality can stay the same or change slow and gradually throughout the years.
So, the bottom line is: if you want the change, you are the one who has to make up your mind and to take action.
