Recently, I read "Why Didn't They Teach Me This in School?: 99 Personal Money Management Principles to Live By" by Cary Siegel.
It's not a "Prepper" book it's a financial book. So, I'm not going to spend a lot of time recommending it here. However there was one chapter, which stood out as something that should probably be applied to our "hobby". It was titled, "Have an Emergency Month Every January".
The premise of the chapter was that once a year, you and your household should live as if you are flat out broke financially. That means no spending on luxuries.
It occurs to me that the same principle can be applied to prepping. Pick a month of the year to stress test your plans. If you have food stores, use that month to cycle though the older goods instead of buying new food or going to a restaurant. Use your gas stores instead of going to the gas station. At the end of the month, replace what you used. Live your month as if plan A is not an option and plan B is life as usual for the month.
All of our plans look good on paper. But we all know that plans go to shit once they are implemented. Waiting until SHTF is too late to hope your plans work. But having a test month every year will help you find holes in your plan.
Anyway, that's just an idea I had.
