Do we need validation from outside to prove our self worth?

I don’t think so. I think only the children need to be praised from time to time and they need encouragement at every stage. But we, as adults have already formed our own opinions and we know who we are and how valuable we are, why do we need validation from others to prove our self worth? Don’t we trust our own opinions? I look into the mirror every morning and say “Mirror, mirror on the wall.. you better agree....I am the best” I feel good about myself but if people don’t agree with me during the day then I am sorry for their poor judgment that they fail to recognize the beautiful me…..it is their loss…. I am not dependent on social validation, if I don’t get invitation for a party or an outing, I am glad that I get an opportunity to spend quality time with some one whose company I truly enjoy….My normal life is never disturbed by this........if we depended on validation for our every action and failed to receive any, our self esteem would be completely crushed. It is important to have faith in one self and believe in oneself and not to walk in any ones’ shadow, we can't be wrong if we are sure what we do is right and we are willing to take full responsibility for our own actions and will face its consequences. It is the choice we make. A choice of responsibility to control our own life
