People with character live what they believe. Even when their values remain unstated, they shine through the personality like a light through clear glass. These are people who are at peace with themselves. They have not only met the challenges they were given, but done so in a way that does not betray their core values. Or if they have betrayed them, they have been willing to see this, admit their error, and make amends. They are not perfect people (God forbid), but they are certainly people of substance.
