Having high-self esteem is a good way to keep confidence up and create bully resistant people. Someone with high self-esteem is less likely to worry about what other people think of them and more likely to be a creative and innovative person. People with high self-esteem are also more likely to make healthy choices in their daily lives and to be more aware of their choices as they effect others.
Yes. Having high self-esteem is representative of a healthy person. Not just physically healthy, but mentally healthy as well. We are all made a bit differently, and we should feel comfortable with the way we were made. If that means getting some help from a plastic surgeon, then so be it. People have a right to feel good about themselves, regardless of the situation.
