How can we achieve life-long happiness

People had been looking for true happiness since the day they realized their existence in the world. However, happiness is a kind of temporary reaction from nerve impulse. It is impossible to keep happy for your entire life unless you are sick because of the infection of certain virus. But what I'm going to talk here is not the real happiness defined by scientist. It is an inner state of what people feel. So how can we achieve life-long happiness?

To answer the question, we must find the reasons why people are not happy and happy. The reason for unhappiness is that there are too many things that we are not able to control and out of our expectation. The reason for unhappiness is that we haven't realized that there is always a choice for us to choose. The reason for unhappiness is that people make themselves despair and think more about the bad size but ignore the bright size. The reason people are happy is that people feel satisfied and comfortable about what happened around them and what happened to them. The reason people are happy is that they find they achieve or get what others cannot achieve or get. It may be a target or object.The reason people are happy is that they make themselves special and different from others. It it a kind of self value realization or identify. After aware of these reasons, it is not impossible for us to keep happy everyday. Actually we can simply keep a good inner state to achieve life-long happiness. Then how can we keep a good state everyday? That's most important part.

To keep a good state, firstly, we need to improve our knowledge. This knowledge needs not be scientific. It can also be common and even just the facts happened around us. secondly, we need to have a good living environment which is very important and affects a lot. It is obvious that if we lived in a country where wars, floods, droughts, starvation happen frequently, we cannot concentrate ourselves just on our individual life though it is also quite tough. Third, we should always be able to think about the bright size more than the dark size. Finally, we should know when to be satisfied. Most of the people who are not happy is just because they never feel satisfied. They always want more or more perfect. In fact is is themselves who make them unhappy. The only thing we should always remember is that: always keep a good inner state.
