It is the ego that tries to tell you are happy only when something good happens to you from outside, if you acquire a new home, a lot of money in the bank, or if you acquire possessions, cars, that will make you very happy. And it is true you are happy for a while. But then this changes. You get used to this situation, you therefore need new things. You need new people in your life. You need new playmates, new toys. (Robert A.)
