Behave as you are

Self-assurance is a really good thing in communicating of any kind. If you behave as being self-assured this can be very decisive for you. People strong in the Self-Assurance theme feel confident in their ability to manage their own lives. They possess an inner compass that gives them confidence that their decisions are right. In case you say or do something wrong but show forwadness, people around you may think that they are mistaken. Thus, later it may prove you've shown off but it'll be too late.
This helps to stand against some of objectionable advice - you just show your own experience without any comments and the person stays outside (referred to http://www.cartoonstock.com/)
