We all know that happiness is not permanent. Happiness does not depend on money, happiness depends on mind. These poor children are lying, they do not have any place to live, no guaranteed food security . If they just get a little,they are happy. One study found that those who are poor are more happy than the rich. The only reason is that the poor are less wanted. There is no 1000 reason to be happy for the world, because one reason is enough. And that is the satisfaction of your mind. Writer Humayun Ahmed said that this is the biggest achievement I am living on earth. There is no greater happiness than actually living. To be happy, we have to learn to love one another. It is said that heaven is not far away from hell, it exists in the human.
