“What is it then to be properly educated? It is learning to apply our natural preconceptions to the right things according to Nature, and beyond that to separate the things that lie within our power from those that don’t.” Epictetus, Discourses.
Understanding where power lies helps us with regulating our emotions. Allowing yourself to be upset about things not in your control – by wishing they had not happened or hoping that in the future things will turn out the way you want them to – is as useful as chanting “rain, rain go away, come back another day” in the belief that your effort might, just might have a magical effect on the weather.
Educate yourself as to what you can control and what you can reasonably influence, and what you have no control over. Take all necessary measures to stay safe, and recognise the power of Nature. Do your best. Don’t take chances.
