I bet you have mastered the selfie; the question now is have we mastered the self?
There is a difference between an image and the true person. The image should not be a cover up or a pretension of the person but the real person should make the image connect with reality and this is what makes it beautiful.
When an honest and competent person gives us a negative comment we should be grateful and take that as a feedback designed to improve the self. But when a dishonest, unethical and incompetent person accuses us of being hard and stubborn, then take that as a compliment. They are operating on different standards.
There is power in the ability to evaluate the self. The key however is objectivity and we may be blindsided. This is why feedback from people we trust is important and we should be willing to accept correction. Successful people are always evaluating and improving themselves. The ones who do not are are usually evaluating and judging others.
