There isn't anyone around, who has not experienced and does not keep on experiencing some very deep persona needs. It doesn't matter what their race or colour or sex or age may be, whether they are newly-born, children, teenagers, your or old adults, everyone is the same. Actually, no person alive does not experience the need to be happy. The answers will be the same., whether they answer with a show of hands or fill in a survey form for someone doing research for a psychological paper.
Every person seeks happiness.
Everyone seeks to avoid its opposite, and is in distress if he or she cannot find he way to achieve what their whole personality. Wants to have. It is the need to be loved and to love. You can recognise it in children. Some have such a longing that subconsciously and unknowingly they will seek it by running away even into a danger of which they are ignorant.
