If you wholeheartedly accept and love yourself the way you are you are centred and being your true self. In such a state other’s people’s opinions concerning your person and way of being no longer affect your inner feelings of well-being and contentment because you are no longer trying to be something outside which you are not inside.
Also, you no longer meet anyone who „is out to deceive or to (mis-)use you“. Because you are no longer deceiving yourself about how and who you truly are.
