Temperament

In psychology, the term temperament refers to the characteristics and personality traits that we are born with. This explains why there are some "easy children" and some "difficult children". Temperament is the first part of our personality that shows up almost since we are born and it can be shaped but not changed, this temperament will affect our behavior through our lifespan.
