Money might not bring happiness to all of us but money in one way or the other influence our happiness. The truth is that no body want or wish to be poor because they want to eat good food, send their children to good school, put on good clothing, have a comfortable shelter and be able to meet up our expenses and talk freely when our mate are talking tell me don't we derived joy and happiness in all those things. I will say money contribute to 70% of our happiness.
