There are a few theories as to what defines our traits to create our personality
According to one such theory, Dan P. McAdams claims our personalities develop in <span>three </span>stages:
<span>Our genes cause genetic mutations forming a 'draft' personality.During our early upbringing, our parents, teachers and friends treat us differently based on our looks and draft personality.Once we are older we then form a narrative of our lives based on our experiences growing up, and make decisions consistent with the character we have created.</span>
So our traits started from slight genetic variances, which effected how we were treated, which then shapes our own self-narrative. So really, our personality is one big story that we tell ourselves, and our childhood was the prologue to that story.
