In the field of psychology and psychotherapy, it is a learnable skill and mode of communication. Dorland's Medical Dictionary defines assertiveness as: a form of behavior characterized by a confident declaration or affirmation of a statement without need of proof; this affirms the person's rights or point of view without either aggressively threatening the rights of another (assuming a position of dominance) or submissively permitting another to ignore or deny one's rights or point of view.[3] Think of specific situations when the communication went terribly wrong. Think now about the impact you had on it. You cannot change others, but by being assertive, you can improve the situation! For example, if you feel that your parents didn’t allow you to build strong self-esteem, this you cannot change. What you can change, however, is to take responsibility for your actions now and in the future in order to overcome your insecurity. In short, transform paralysing thoughts in actions.Remember, individuals arecapable of drawing nourishment from cultural differences and similarities.
