Stop looking in the rear view mirror...it's not where you are going. (Told to me by kindly exJW on here.)
Most people are doing the best they know how. When we know better, we do better.
You can't change what you don't acknowledge.
The Four Agreements...I use daily;
-Be impeccable with your word.
-Don't take anything personally. (Hard to do)
-Don't make assumptions. (Really hard to do.)
-Always do your best.
