There’s a point you start getting inverse correlation between wealth and quality of life. My life couldn’t be happier. In fact, it’d be worse if I had six or eight houses. I have everything I need to have, and it doesn’t make a difference after a point….good housing, good health, good food, good transport. When you get to 10 times, or 100 times, or 1,000 times, it doesn’t make a difference…Success is really doing what you love and doing it well. Really getting to do what you love to do every day—that’s really the ultimate luxury. Your standard of living is not equal to your cost of living.
—Warren Buffett, CNBC
