You can be competent to some degree without skill mastery, but a professional shouldn't be satisfied until they can do it right. He or she should be willing to practice until they are confident they can't do it wrong. This doesn't mean you won't make a mistake. It means you won't quit until it's right. Character Competency equals skill plus character, according to Stephen R. Covey, author of First Things First and The Seven Habits of Highly Effective People.
Character is at the core of competency.
It implies integrity and the possession and expression of various virtues, especially honesty and goodness. Character, to a large degree, is dictated by self-concept. Self-concept is derived from public perception and private awareness. Often people are consumed with the public's perception of them. When private awareness of their own faults violates the public perception of their virtues, self-concept is deflated because they know who they really are.
