The proper use of impressions cause no harm.
The main trait of a virtue is to practice doing good for yourself and others.
It is biological, everyone learns to do good.
To decide on right action is practical when the following rules are applied: it is better to start by deciding not to act on any desires but only aversions.
Also apply the additional caveat: make the aversion small enough to guarantee success and as confidence and boldness evolves increase the size of the aversion in good measure.
Lastly, practice using the proper use of impressions in private as much as possible to maintain a peaceful atmosphere and optimal performance of said practice.
The best outcome is to practice daily for life whether you feel like it or not.
