Look at a thing from many perspective

The day I went back to USM from Kuching, I sat inside the airplane and look through the window, I noticed that the rain is not only can fall down but can also fall behind. This make me remember that, sometime when we are facing problem or something else, we should always change the ways of our thinking. For example when we are unhappy because of something then we should change the way of our thinking on the thing, we might able to find the happy way for the thing.
