The world keeps changing, it is in her nature. And while even the tiniest actions can have grandiose effects, accidents will happen to us that we will not be able to avoid or counter, no matter how hard we try or what we do. Such a thing would not happen to us because we are singled out by life or god or the universe or whatever you call it. The occurrence of an accident is purely statistical. Therefore it is only us who can and are supposed to decide how we will react to the issue and what we will make out of the situation. It is all on us.
