Dear Folks,
I've been really trying to get friends, family and others to understand that being flexible particularly in, during and after an economic challenge is THE KEY to maintaining not only your life style but also your sanity.  If you can grow some of your own food, have two possibilities for income (trade/skill and a 'profession') you can do more than merely survive - you can thrive.
I would encourage you to really think about this, not as a what-if-doomsday concept but really how you can better control some or many aspects of your daily lives.  In other words how can "you control" your resources. 
As an intellectual exercise consider what you would not only need in a crisis, but also what resources (product or talent) would be needed by others.  Want some ideas?  Look at craigs list to see what people are selling or looking for. 
Here is a nice list of 10 reasons for being self-sufficient, plus the link to the original article  -- Please share this with everyone.  You do not have to get property in the boonies to be self-sufficient and you do not have to do it all.  Even some aspects can dramatically improve your lives.

10 Reasons to Become Self-Sufficient
- Freedom from market manipulation  – The traditional market-driven investment vehicles are more and more  obviously controlled by traders and banking institutions.  The debacle  of the private Federal Reserve Bank is just the icing on the cake to a  previous decade full of Ponzi-type schemes.  Now, the institutionalized looting of retirement money is being planned.
- Hedging against inflation – Have you noticed the price of goods lately?  Even Wal-Mart is silently raising  its prices.  People might have a choice whether or not to buy stocks or  gold, but people have to eat — the current increases in basic goods  portend hyperinflation, and will not ease anytime soon.  Food shortages could make the problem exponentially worse.
-  3. Increasing health and wellness – It has now been revealed that some “organic” items have been falsely labeled.  In addition, a host of “GMO-free” brands have been exposed as deceptive.  GMO food lacks the nutritional value of what can be grown in the average backyard.  GMO mega-corporation, Monsanto, has a sordid history and has continuously trampled on our trust.  It is time that we do the work ourselves.
- Building community strength  – We constantly hear people say, “I don’t even see my neighbors, let  alone know anything about them.”  Of course not:  80-hour workweeks and  grabbing meals-to-go doesn’t exactly promote community interaction.   With such little time to interact with our immediate community, it is  no wonder why many people report feeling disconnected.   In these trying  times, it is a local community that can offer the best support.
- Working for yourself – Working hours are increasing, pay is often decreasing, and corporate executives are taking bigger bonuses  than ever.  This is leading to a prevailing disgust, as people are  being forced to admit that they are living lives of near-indentured  servitude.  Even for those not working in corporations, working for  someone else is rarely as satisfying as creating and working for  something where every minute you spend is yours alone.
- Having more free time  – We have been taught to believe that life on a farm is arduous sun-up  to sun-down drudgery where you collapse at the end of the day.  This is  not so much the case anymore.  Sure, the setup of any farm or  self-sufficient endeavor is often time-consuming and laborious, but new  technologies and new skills of manufacturing food via permaculture and aquaponics  are offering low-cost start up and minimal maintenance, as these  techniques serve to create symbiotic systems that are remarkably  self-governing.
- Generating food and energy security  – The planet is running out of food and traditional energy. Climate  volatility, market forces, GM foods, and rising costs of harvesting and  transporting food are all conspiring to create food shortages  even in the First World.  This trend will not reverse.  And our  oil-soaked way of life is being threatened by mounting evidence that the  oil lifeline could be disconnecting rather soon.  We should be looking  to the air, sun, geothermal, and wave power to wean us from the energy  grid.
- Acquiring an appreciation for life – As  one gets closer to life-giving forces, there is a natural appreciation  for how things come into being.  When you have created your garden,  toiled there, selected the best for harvest, and have prepared that food  for your family and community, the significance of what you have taken  part in can be transformative.
- Restoring balance  – Nearly everything in our society is at a peak, or is drastically out  of balance.  The systems and governments to which we have looked for  balance restoration are missing in action.  We must take it upon  ourselves to restore our own financial and environmental balance sheet.   The best way to do that is to reduce our overconsumption.
- Becoming a producer, not a consumer  – This is the best way to reduce your cost of living and increase your  self-sufficiency.  In the U.S. over 70% of the economy is based on  people buying things. This is a clear sign of imbalance and, by  extension, it is not sustainable.  Furthermore, we also have seen  corporations race to the bottom  to find low-cost production on the backs of desperate people.  The  exploitation of the Third World to clothe, feed, and entertain the First  World is something that most people do not want to think about, but it  is abominable. Again, new technologies are making it easier than ever to  produce your own food, and even your own clothes. 
I hope you find this helpful and encouraging - it is about the positive impact, not the negative.
