One of the most powerful passages i know. If you can identify the source well then that tells you something about me.....
"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 peace 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 by mistake. ........... unless I accept life completely on life's terms, I cannot be happy. I need to concentrate not so much on what needs to be changed in the world as on what needs to be changed in me and in my attitudes."
