The way I see it, you have three choices regarding preparation:

Build a fortress, stock it with enough supplies to last you 6 months.

If you are not financially well enough to do this, then plan to evacuate to a safer location, determining first what the criteria you need to survive will be and where a place is close enough that could meet that criteria. Leave at the first sign of trouble.

or you can do no preparation, then pray to whatever deity you like when the time comes, or rub that lucky rabbit's foot, or spin around on your left heel three times going "Whoop Whoop Whoop" like Curly on the Three Stooges and maybe you will get lucky.

Since I like to take responisbility for myself and don't tend to trust others too much, I opt for the first choice.
