From Courage to Change, page 122:
There are many areas of my life that I cannot change. What I can change is my attitude. Today I can accept my life as it is. I can be grateful and happy, here and now, with what I have.
“Life holds so much–so much to be so happy about always. Most people ask for happiness on condition. Happiness can be felt only if you don’t set conditions.” ~Artur Rubinstein
