peace of mind/peaceful mind.

I know a man called John Smith who is a very unusual millionaire. What makes him unusual is that he has no money. My idea of the millonaire is a man who has a lot of money and no worries that money can not take care of. But John Smith has thought about this a lot. He says that the average millionaire never uses money and always gets other people to pay for his taxis or drinks. This is because he is so used to thinking in millions that small amounts of money are not worth thinking about. But this does not mean he has no worries. On the contrary, the average millionaire worries constantly about his business, his investment and international rates of exchange. A fall in the value of the pound or dollar can give sleepless nights and makes him feel ill. His great wealth also makes it diffcult for him to be happy and comfortable with other people. Are they friendly because they like him? Or do they just pretend to like him because they want his money? John Smith says that he feels very sorry for millionaires who, instead of being masters of their wealth, are slaves of their millions. In one way, however, John Smith always behaves exactly like a millionaire. I mean he never has any money, and generally manages to persuade someone else to pay for his drinks. But unlike other very rich men, he is good value for money-he is full of jokes and fun. An evening spent with him is not cheap because he is usually very thirsty, but he always makes people feel happy. He has no worries about the economic situation, banks, investments, and so on. He does not even give much thought for tomorrow. He is the happiest man I’ve ever met, and whenever I meet him he tells me: "In money I’m not rich, but in peace of mind, I am a millionaire." And then the world’s richest, penniless man usually adds, with a smile, "Do you have time for another drink?" How can I refuse?
