Positive psychology is a recent branch of psychology that "studies the strengths and virtues that enable individuals and communities to thrive". Positive psychology seek "to find and nurture genius and talent", and "to make normal life more fulfilling", not simply to treat mental illness.
Positive psychology area is more concerned with the sunnier side of psychology, which is the area of those people, who are happy and move with confidence, wherever they go and whatever they do. Positive psychology may shed more light on why some people behave in such a pleasing manner and how they have developed that trait. Ultimately, this intense study may help us to find a lasting cure for many of our negative psychological conditions and other eccentric behaviors.
Positive psychology often relies heavily on the principle of optimism, which is a cherished positive parameter of human excellence. There is remarkable evidence that optimistic people are usually happier and highly productive than ultra pessimists. Optimism can also be taught and learned by human beings. According to the new theory, there tends to be a positive flow of things in those people who are highly optimistic and cheerful. This flow is usually not checked in them, in any manner, at any time and thus this set of positive flow causes a person to be tougher mentally and psychologically.
