Sažetak Happiness is undoubtedly a sense of life. Happiness is harmony, first of all in oneself, then with others. Happiness and peace in one's soul are an essential quality of life. Both men and women can be equally happy. Happiness is health. It is a life's gift and goal. It is also an inner liberty. According to Publilius Syrius, happy are those who believe to be happy. Happiness is a state of mind. Beliefs are usually connected with religion. Still, they have a broader meaning. One can believe in an idea, authority, even science. Beliefs, according to psychologists, are acceptance of a principle or reality, accompanied more or less by conviction. One should distinguish between beliefs and faith. Faith is one, beliefs are many. They are both part of our existence. In the everyday life faith is an essential component of everything, even health. The most faithful partner of a doctor is the patient's belief in health. One speaks little about it although it means very much. That is proved by researchers. It is the same in psychotherapy. Faith contributes not only to health but to happiness as well.
