"Lord grant me the serenity to accept the things I cannot change,
the courage to change the things I can, and
the wisdom to know the difference." St Francis of Assisi
For some reason last night this came to me out of the blue, I have not heard it for years but felt a bit poorly with my ticker playing up and went to bed early. Whenever I feel off I try to meditate but needed something positive to hold onto so kept on saying this and it did help.
Maybe in times of stress it would help you.
