How to be the happy person?

How to be the happy person? How to be the person of wisdom? Let's discuss it now.
There was the businessman Mr. Hu who always feel unhappy in life although he had earned lots of money.
One day, a man recommended him to read the student guide for being the good man. After learning it, the outcome was that many people still like to avoid him. He was wondering why? The student guide teacher explained to him because he had no wisdom due to the following reasons:
1.chasing for fame 2. care for own interests only
3. talk people' wrongdoings
4. greed and hatred.
The teacher told him:" As long as you have selfishness in your heart, you will not be the person of wisdom. That means you have to free from all these in order to have clean heart. Without clean heart, you will continue to have the conflict with people, unable to get along with people, so this is the time for you to examine yourself. You ought to put down " selfishness ", then you will be able to have clean heart. After that your wisdom will appear and you will be able to solve lots of problems in life. It will bring back the concept of " love " in your heart. you will definitely taste the joyfulness after helping others."
