I've just acquired a 16 volume set of small booklets by Mors Kochanski. SURVIVAL KIT IDEAS has a very appropriate paragraph " There is a paradox concerning people who get themselves into trouble. It takes one type of person to get into trouble and a different type to get out of it.The person who prepares rarely finds the opportunity to exercise his skills. The person that gets into trouble, likely doing so out of ignorance, is often confronted with problems that tax a well trained person.The best way to deal with a problem is to be knowledgeable enough to avoid it in the first place. This is the lightest kit there is-knowing what you are doing. Of course there are problems over which you may have little control because they are not your fault, outside of you being at the wrong place at the wrong time."
