You can change your personality anytime only if you are willing, I'll know you better by what you do daily so if you change then I'll have to change my perspective of you in my medulla oblangata. People normally e.g the African families usually call the children after the ancestors. A child let's say 10 and above ages are called ancestors basing on their same personalities. It is normally said by the psychologists that what you want to be seen as is what you should portray in your first meeting with each other, usually called first impression in good words. Even if you change after a while the perspective of you that was there won't really change that much, there will be a dim picture of the previous you.
