Hi Fading Begins,
"brothers were told to pack up a "survival kit" with enough provisions to last for six months - water, medications etc."
Interesting and not worse advice one could give. This struck me as Mormon-esq, as they are encouraged to have on hand 1 year supply of food. The local Costco has several items you can see are designed to be bought by those interested in this.
However, if you want to be practical how about this...
Brother & Sisters, try and save up enough money to live several months between jobs.
Brother & Sisters, think ahead to your retirement years, save little by little so you'll have what you need in retirement. Many governments have allow you to put savings into an account that is not taxed (aka 401K, IRA and RothIRA for the USA and RRSP for Canada). Do that.
Brother & Sisters, plan now for your post public school education -- it can be expensive -- but it is a known fact that those who have post public school education will be higher wage earners and have more job flexibility over their lifetime. College and University education oftentimes results in the development of critical thinking skills that in turn can help people see logical fallacies, even when presented within the context of cherished beliefs.
Cheers,
-Randy
