“The way to gain a good reputation is to endeavor to be what you desire to appear.” ~ Socrates
Example: If you are known for embezzling funds in an organization or wherever you hold a title, make a deliberate change; play by the same rules that guide funds utilization in that organization. Never authorize or use funds without the signature or knowledge of owners/stakeholders of the organization. If you follow this rule, before long, the way you are perceived will change, because the status quo (using funds randomly and covering your track) has changed.
Bottom-line: Wrong deeds can be reversed; whatever action you deemed “bad”, make a deliberate move on changing that “bad” action the next time the same opportunity presents itself. That’s how change is made. Correct?
