The Big Book of Everything
“What is the Big Book of Everything?
In a nutshell, it is a notebook filled with all of the information anyone could possibly need to know about you. The idea is that in our lives we have countless things that we are involved in. On rare occasions, other people need this information and no one knows how to get it. That’s where the Big Book comes in. By filling this out and keep current, you can simply the effort others have to take on your behalf.”
This is great for emergency preparedness, and a good location for all that info that you rarely need, but have to retain. (Such as life insurance policies, bank account numbers etc.)
