In doing some research, I found the remainder of the text for that prayer … and I actually find the rest of it to be even more powerful than the more well known exerpt:

Living one day at a time,

Enjoying one moment at a time,

Accepting hardship as a pathway to peace,

Taking, as Jesus did,

This sinful world as it is,

Not as I would have it,

Trusting that You will make all things right,

If I surrender to Your will,

So that I may be reasonably happy in this life,

And supremely happy with You forever in the next.

Amen.
