is the essential factor to influence happiness? Virtually happiness is a kind of feeling and emotion, which can be obtained by the endeavor of us. Whether a person is happy or not is mostly decided by his attitude towards life.
To be happy, firstly, we should try to understand that life is not easy at all to all of us. Difficulties and pressure exist everywhere during our process of making a living. It is unnecessary to complain about it and even become pessimistic. Secondly, it is important for us to confront our life with right attitude, to be active and grateful. In spite of suffering from disasters, instead of being sad and negative, we should try to maintain the faith that tomorrow will be another day. We often hear some people saying "I have no choice now." However, this is totally wrong. In fact, at this moment, we still have a choice, to be happy or unhappy.
Meanwhile, to be happy, we have to pay attention to two important points. One is that we should not try to build up our own happiness on she basis of others＇ misery, because that is not real happy. The other is that we＇d better not to pursuit happiness merely for the aim of being happy. If we do so, we will lose more than what we have got.
Above all, no matter what our life will be alike, we should take an active attitude towards life. Don＇t take everything for granted. Feeling our life with a grateful emotion and being open-minded, in that case, we can be happy.

Moreover, thanks to the one-child policy, more energy was saved for our descendants.

Dear Harry,

Have you been in Melbourne? I'm really sorry that I didn't see you off. Because I must return to school before February 24th. My school began on the 25th. I just hope you have a good trip.

Although we have been in different countries and do different things, I still can't forget the holiday that we spent together. After we graduated from middle school, we kept in touch with each other frequently, so the friendly feelings always live in our hearts.
