There is an interesting article titled [It's not easy being
a billionaire] by Michael Johnson, published in Business Times on 5
April 2008.
The author said that there is no such thing as having enough
money, for the super-rich agreed that the more you have, the more
you worry about it.
Studies have shown that once a person has sufficient money to meet
his basic needs, more money does not add anything more into a
person's real happiness or well-being. While Spiderman can said
that "With great power, come great responsibility", billionaries
will said: "With great riches, come great unease."
that's because they still working.
if i got 1 billion i will stop working.
but wah lao no chance to prove it.
