Have you ever tried controlling an adult? It is useless. Children are the ones who need such control, instruction, or guidance. But when you and others grow older, you just have to let it be. You have to let it be, and to not forget that the easiest way to stay sane, in the midst of whichever chaos is to control yourself. Don't waste your time trying to control external factors. Instead, take the time to know "you" in depth, so you can control your reactions to the ups and downs of life.
