" Vulnerability — Being unguarded or undefended in expressing one’s thoughts and emotions. Most men hide the thoughts and emotions they believe will make them less attractive. This forces them to behave conditionally and base their behaviors on the beliefs and perceptions of those around them. This is unconfident behavior and ultimately makes them unattractive. Paradoxically, making oneself vulnerable and surrendering to criticism and not expecting anything in return from others causes one to build self-esteem, become more confident and more attractive. "
