Happiness can be described as a positive mood and a pleasant state of mind.According to recent surveys£¬sixty to seventy percent of Americans consider themselves to be moderately happy and one in twenty persons feels very happy.Psychologists have been studying the factors that contribute to happiness.It is not predictable£¬nor is a person in a clearly ideal situation necessarily happy.The ideal situation may have little to do with his actual feelings.
A good education and income are usually considered necessary for happiness.Though both may contribute£¬they are only chief factors if the person is seriously undereducated or actually suffering from lack of physical needs.
