Other people’s happiness
(一) Happiness from lower-level citizen
In the eyes of people who living at the bottom of society, happiness is also simple. Their happiness may be to work hard at their jobs and spend their free time with their families. The happiness of those at the bottom is all based on having enough to eat and drink every day. And they are content to settle down and not take risks. So their happiness is pure and beautiful.

Teachers'work is hard, tedious and repetitive. But teachers have their own unique happiness in their work。 they repeat the same thing every day, which is tedious . But if teachers can adjust their mentality, find happiness in the changes of students and their growth, it will be different.
What is happiness from the teacher's point of view? A good lesson is happiness. The process of discovering knowledge in teaching and students'community experience is happiness. The sensitivity of teachers' own thinking is happiness. In teaching, they feel that education is interesting and satisfied.

What is the doctor's happiness ? Only the doctor himself can understand .One the father of Chinese surgery, said in a speech that "the real happiness of a doctor is to exchange his own intelligence and work hard for the rehabilitation of patients!" Doctors are required to "constantly think and deeply understand what is a doctor's real happiness."

A successful businessman, I think his success lies more in his discovery of value and acquisition of value. Among them, he not only refers to money, but also morality, benevolence and justice, knows the warmth and coldness of human feelings, and follows the rules. Most importantly, he is very happy and never feels lonely and bored because of money.

Our own happiness
(1)When we were young
When we were young, all we had was simple happiness. At that time, we were very relaxed, our understanding of friendship was not very deep, and family affection occupied most of our lives. Sometimes our happiness was a sweet candy, a teacher's praise, or our parents’ encouragement, our happiness became some small happinesses. At that time, happiness was simple and easy to satisfy.

(2)At present
Now we're going to start putting something on the unexpected list, such as the brand of clothes, shoes and bags. Occasionally, you will be very happy because you have something you didn't have before. This is material happiness.
Of course, at this time, we also have the support of friendship and family. The company of family and friends can also give us unexpected happiness.so never forget you also can make happiness be more simple and easy.

(3)In the future
Ten or twenty years later, we are probably the happiest because we have three kinds of emotions, family, friendship and lover. Ten years later, we take care of our family ，hope they would be healthy,have some very closed friends ,and perhaps find our lover and have our children. These are all can be our happiness.
In a word, ten years later, just don't forget your original heart then get the real happiness.
