Don't stop doing good or even stop trying.
A person who does good, means he is done with himself, he has no problem with himself. As you said, has made peace with himself.Very wise @rima11 ,
There are concepts that we can apply in doing good, so that good deeds will never disappear and always grow in anyone, namely:
"Forget immediately the good you have done to others - Always remember the good that others have done to you."
