I'm looking for an existing word that roughly means "the process or idea of replacing bad/negative elements/deeds with good/positive elements/deeds, such as when a negative thing is eliminated at the same time that a positive thing is added".
In terms of words that would not fit this goal are words that could (to some people) mean only the elimination of bad or the addition of good without the other half.
Here is an example sentence showing the usage:
I live my life with _____ so that I'm not just removing bad habits, but I'm filling the hole created by removing the bad habits with the addition of good habits, which both maintains my ability to fight returning to the bad habit while also creating a positive element at the same time.
