In a survival situation, there is no replacement for a positive mental attitude. It weighs nothing, is invaluable and develops, in part, courtesy of these preparations, at no extra cost. A final thought to leave you with. Very few homes are consumed by fire.
Few people can even say they know someone personally who had a house fire.
Yet, few would question the need to carry fire insurance on one's home, though they may grumble about the cost at times. Sure, you can wish you never need it. You could even rationalize not having it because the risk of the house burning down is so small. But, you carry insurance anyway because the consequences of a fire are so terrible, so devastating and so costly and the expense of insurance so relatively small in comparison. Certainly, insurance isn't a perfect solution, but it's the best answer to a very real possibility.
