Difference between Personality and character ethic:

Character Ethic focuses on foundational traits, including integrity, humility, hard work, loyalty, self-control,
courage, justice, patience, modesty and morality.
These are basic principle that any person in any culture or time period would agree

Personality ethic and characteristic ethic is determined by each individual person but also can be influenced by social norms
Humans are social animal and everyone wants to get associated to a certain race,group

To try to fit in to a group we follow the most encouraged habits,actions in that specific group

The more the environment YOU live in encourages character ethic not temporary fixes (personality ethic) the more people will be inclined to work on their character ethic

On the other hand personality ethic focuses on skills and practices that affects YOUR public image, attitudes, behaviours
This approach focuses more on quick fixes
How to be more charming, have a more positive outlook, make people like YOU, and influence people to do what YOU want

These solution offers and work temporarily while the underlying cause is always overlooked

Character Ethic primarily focus on primary trait
While personality ethic focus on secondary trait like communication skills, positive thinking, and interpersonal strategies
Which are essential for success but they are ineffective if they are not based in system to support them

For example
YOU try to use communication skills to make people trust YOU but YOUR character is not honest and trustworthy
the effects will be hollow and eventually people will see through the act

Working on personality improvements without first establishing the necessary character traits would be like a farmer trying to fit all her work into one season
YOU can't shortcut the process and can't ignore the difference between character ethic and personality ethic when YOU need both for self improvement

Understanding the perception behind every action and be open to change it if its wrong or to think from other person perception is the starting point to work on character ethic
