Balance. Desirable? If you can be embarrassed/ashamed/humiliated/apologetic is that an offset to being conceited/arrogant/proud?

Some are PROUD 24/7 and never humiliated/ashamed/embarrassed/apologetic. What's wrong with them that they are so wackily out of balance? Does it happen at conception or did mummy and daddy dearest tell them how perfect they were and they believed that crap?
