Sometimes you see a miraculous phenomenon. Or you wish so. However, true miracle does not exist.
Every result has its own reason. More or less, there is a relation between cause and effect.
A miraculous success results from an assemble of enormous attempt. In contrast, a terrible failure is usually brought by the combination of multiple mistakes. It is possible that one misfortune leads to tragedy, whereas there is no triumph only by chance.
You can be proud of your success. Meanwhile, it is stupid to hope a satisfactory result without any endeavor.
As to say, "Heaven helps those who help themselves."
