A person with high confidence will be really competent and a person with high competency will have real confidence.

Ideally everyone should focus on both and perform every task in life with maximum confidence and competence.

Both can be enhanced with the help of positive self affirmations and by doing really challenging and tough tasks.

Confidence is the self belief that you can perform whereas Competence is your real capacity of performing.

There's a famous quote, which is really true, on confidence by an unknown author. It says ‘Confidence is like a muscle: the more you use it, the stronger it gets’.

No human being will work hard at anything unless they believe that they are working for competence — William Glasser.
