Similarly, most things that bother us today won't really matter a few years from now.
So how should we behave in the face of crisis? Answer: Just deal with them moment by moment.
In reality, we can always handle the present. It is only the thought of the future that frightens us . .and the problem is that our minds tendency is to drag us into the future.
So when scared of what may go wrong someday, just say to yourself: "This too shall pass".
