I love this artwork! Also, I have always believed this prayer is three steps in itself: 1) gaining serenity to accept, 2) having the courage to change what we can, and 3) gaining wisdom to know the difference. This realization really helped during my first months in Al-Anon.
An unresolved past never goes away until you find the courage to let go of all the pain and accept that there’s nothing you can do to change the past. What’s happened has happened and what’s done is done.
