Don't worry, be happy!

Don't Worry, Be Happy，非常欢乐的一首歌，一听就喜欢。

In every life we have some trouble
When you worry you make it double
Don't worry, be happy......

Put a smile on your face
Don't bring everybody down like this
Don't worry, it will soon past
Whatever it is
Don't worry, be happy

有些很大的trouble，几年以后回头再看其实都不算什么trouble。所以吧，乐观点就好，don't worry, be happy，哈哈！
