Happiness exists everywhere. Everyone has a different definition to the true meaning of happiness. Some people think possessing a great deal of money is the secret to happiness, while others feel giving aid to others makes them happy. I approve of the latter there are many poor people in our society, and we can contribute some money to charities to help them. When the poor receive our assistance, their lives will improve. Smiles will appear on their faces, and this is the best reward we can get from helping others. Regardless of gratitude of price, we should help others from the depths of our hearts. When we see their happy smiles, we will be happy as well. So I think that true happiness comes from the mind.
