Another thing that helped me long ago in stress reduction is the 2 principles of:
Getting a book on Choosing Simplicity was one of the best things I ever did. To this day I have no clutter, no worries about personal property and keep everything to what is essential.
Also the whole awareness thing just keeps me in the moment analyzing what is really going on, what I really need to focus on, what is really important to do today and leave everything else for others to worry about.
In the end...since you dont know how long you will live, just do your best to make your life more peaceful, fun, rewarding and enjoy the daily ride. Control what you can...and don't stress out over the stuff you can't.
