Acceptance (AKA Page 449, Page 417 or acceptence)
Acceptance was an idea in a personal story introduced in the 3rd edition and stories are not included here. It was not part of the original book.
See page 449 in the 3rd edition or page 417 in the 4th edition.
It says in part:
And acceptance is the answer to all my problems
today. When I am disturbed, it is because I find some
person, place, thing, or situation—some fact of my life
—unacceptable to me, and I can find no serenity until
I accept that person, place, thing, or situation as being
exactly the way it is supposed to be at this moment.
Nothing, absolutely nothing, happens in God’s world
