Everyone says something about life.Music,money,success,car,family,etc.To me, life is happiness.What makes us happy? The real question should be that.My little daughter makes me happy.My wise boy makes me happy.My beautiful wife makes me happy.My dad's health makes me happy.My mum's smiling voice makes me happy.If so, what makes the world happy? Religion didn't.Capitalism didn't.Nationalism didn't.I learnt that most people should find out a way to be happy in order to reach the real happiness.Maybe, some might ask why I stress the happiness continuously.Because it is the source of peace and tranquility.
