Grant me the serenity to accept the things I cannot change.
The serenity prayer was composed by American theologian Reinhold Niebuhr in 1933. Its original composition was slightly different, but it has been adopted by many groups, most commonly recognized as a mantra for Alcoholics Anonymous. Niebuhr's prayer originally asked specifically for changing things that must be changed, not things that simply can be changed. Bottom line is, enjoy a cup of tea while you decide where to put your energy. And drink it from this mug to remind yourself.
