Wealth consists not in having great possessions, but in having few wants. (Epicurus, 4th century B.C. Greek philosopher)
For many in the more affluent societies of the world, the mindset seems to be that having more is a guarantee for happiness. But real wealth is not about what you have in material things but rather what you have in character and integrity. Then, you can be satisfied without wanting more and more.
Whoever loves money never has money enough; whoever loves wealth is never satisfied with his income. (Ecclesiastes 5:10)
