Are we headed that way again? Many seem to think so. The thought of a financial disaster doesn't frighten me as much as the thought of what people do when they panic, and what our governments will do to try to "fix" it.
If you understand the basic principles of frugality, you'll be in a much better position than most people. If you have a well stocked pantry, the skills to repair and maintain your home and clothing and so on, and have planned in resources like a garden, you'll be a blessing to yourself and others.
"Off the Grid News" ran an article called "9 Forgotten Survival Lessons From The Great Depression," which covers, amazingly enough, many of the things I have taught, preached and ranted about over the years.
I would only add one thing and that's the importance of community. Whether it's your neighbors or family or friends, deliberately surround yourself with others who have similar interests and thoughts. You can trade skills, goods and encouragement if you have a good community to do it within. It's hard to go it alone.
Start now if you haven't already. Gain those skills, stock your pantry, get out of debt, create your community. You may very well be glad you did.
