The best way to defend yourself against the risk of 'losing it all' is to have an important part of your wealth stored between your ears, where it can't be taken from you.
If bad fortune should intervene and you lose your financial wealth, or you need to move away from your current community and start all over again, you'll be able to build a future if you have valuable skills, knowledge and expertise to rely on.
This will be especially true if the future unfolds the way we expect, where declining energy yields and economic stagnation sentence us to doing less. In such a world, a much higher premium will be placed on those individuals who know how to create value. Who know how to get things done.
