Two words - Be Prepared.

Snow is forecast for next week, maybe. Prepare today with what you will need next week.

You live in hurricane/tornado/earthquake alley. Prepare now for no notice/short notice events.

An asteroid is coming to hit the Earth. Buy lots of beer and chips and have a party, it's all over but the shouting kids.

Being truly prepared means that you worry about stuff you can change, and don't worry about stuff you can't change.
