Positive psychology is a branch of the conventional psychological theory which has a big focus on well-being. Sometimes described as the study of what makes a life good, it aims to deal with individuals and societies on an equal footing to ensure that positivity is maintained in all situations. It is often seen as a reaction to psychoanalytical techniques and so-called behaviourism which tend to have much of their focus applied to psychological problems and mental health conditions. Instead, the principle is to find out what makes people happy and content and to place much more of an emphasis in such areas. To some, it is the study of eudaimonia – a Greek word – that roughly translates as happiness or welfare.
