The purpose of life is to be happy but we can attain happiness only when we spread vibration of happiness by our good conduct.Spiritual perception grows in happiness and good behaviour towards our fellow person,parents,brother or sister,elders or younger-our dependants and harmony brings trust,love and happiness.
To be good is goodness defined by self control, crystal clear thoughts and strong character.It should be the main object of one's life rather that rich and comfortable life.Because possessions are not source of happiness though they give us satisfaction or boost our ego.So watch every thought and action.Cause of wrath,delusion or loss of memory and  intellect is our attachment towards worldly goods and relations.Good conduct reflects your character,your upbringing and well being of your family's  behaviour.
