the boundaries of personality / border

I'm trying to define human condition, human nature. To find answer to questions: who we are? I'm asking of the boundaries of human personality. What makes as feeling ourself? What create the personality? Is it character traits, preferences, repetitive behavior, felt emotions, experiences? What makes the personality consistent and what factors can destroy it?
Very important fact is also the way I create the drawing. It was hundrets hours, working in a trans like monk who writes the mandala. A kind of meditation. It was time to contemplate yourself, to clean the mind from many stimulus surrounding me.
