Recently, because of some significant financial changes in our life (including moving halfway across country, one of us unable to find work and the other getting laid off, and then getting a job at 50% of the previous salary) we are no longer able to invest as we done in the past. However, because we invested in prepping prior to our sudden reversal of fortune, what would normally happen in this type of financial emergency merely became a financial irritant. Even without 75% of our previous income, we are still able to live well and continue our prepping effort, if only on a reduced scale.
There are several things that many of my non-prepper, and less well-to-do friends, say that prevents them from prepping. The top three excuses that I hear are:

I don’t know where to start I don’t have enough money to invest in prepping It’s too late to prep; if I haven’t done it by now, I won’t have what I need when TSHTF.

These are the responses our family gives to those who don’t believe they can, or should, prep:

Not knowing where to start is no excuse. Every person knows what he or she will not eat. Every parent knows what their children’s favorite foods are. Get your kids involved to let them pick their favorite foods and give them a chance to learn about food storage along with you. Start a list of what your family likes to eat. Pick favorite meals, treats, and drinks. Then create a customized list of items that it would be useful to have extras of in your home in an emergency.
