Charles Martin. Between us the mountains (№ 314961)

If the worst possible, it is better not to stick your head in the sand, not to hide from the worst, not to flee. It can happen. It is better to prepare for it. Then turning your worst guess in reality will not knock you off your feet.
If the worst is a possibility, then you keep it on the table. Don't hide from it. Don't run. It can happen. And if and when it does, you need to have thought about it ahead of time. That way you're not crushed when your worst thought becomes your reality.
