“A man without a smiling face must not open a shop“. – Chinese Proverb. And indeed. Let’s take it from the known businessmen and traders since their early ancestors, the Chinese. It is not just being frugal to save much, but a smile will bring more success to you. And it is free; it enriches those who receive it without impoverishing those who give it, and it is also good for the heart. And not just for business people but for everyone. For nobody needs a smile as much as those who have none left to give.
