I have the _Get It Together _ workbook from Nolo Press.
This book offers an organized approach to collecting all the necessary records and information that will guide the people who may need to step in if I die or am incapacitated.
For example, I have made sure that all my bank accounts and investments have the necessary riders so that upon my death they will immediately become available to my wife and daughters, avoiding the cost and delay of probate. And I have arranged a loving adoption for my dog if it's needed.
I'm in the process of making cremation arrangements with the Neptune Society so that my body will be taken care of with one phone call.
As I complete taking responsibility for these things I am feeling very free to give all my energy to filling my remaining life with joy, be it days or decades.
Speaking of decades, I also suggest that everyone create and maintain a ten year life plan, really naming and writing down what you want to do. Don't let it escape you!
