For many years, I have been constantly searching the country and the vast world to find where happiness comes from, and I met a wise gentleman. Because when I told the story, I was given a meaning box because it has only one word: SMILE. Yes! You, smile. Smile in spring and summer, smile in your dream. Smile in the clear sky, in the sun, in the cloudy day, in the pouring rain. Smile at your loved ones and friends, even at your enemies and enemies. It's all you do for happiness.
