Happiness is the most precious thing in the world, which can be obtained in different ways.
From my point of view, being in a good mood anytime and anywhere is the first thing for those who want to be happy. There is an old saying going like this, "happy is he who is content." I can't agree with it any more. I still remember a story my mother told me when I was a child. A millionaire tried every means to seek after pleasure but to feel unhappy. It's not unique, but has its counterpart that poor men to whose name not having a thing always feel happy. Why are they so different? The answer is that the rich is being thinking how he can gain more while the poor is satisfied with what he owns at hand-health, freedom, love and so on.
Furthermore, love makes great difference to happiness. If you have love in your heart, you will have happiness in your life. Love consists of two parts, one is to love others, and the other is to be loved by others. Lei Feng set a good example for all of us. He served the people wholeheartedly until the last minute of his life. He regarded serving the people as the happiest thing. There are numbers of similar inspirational stories to be found. In addition, being loved by others can also lead you to happiness. Courage from your parents when frustrated, care from your lover when ill, help from your friends when in trouble… all of these will make you the happiest person in the world.
The last but not least is to act happily. Putting on a happy face and thinking interesting things are helpful to trigger happy feelings.
Wile happiness is precious, it is easy to get.
