If someone puts you on pedestal or you're putting someone there, know that it's a recipe for disaster. Sitting on a pedestal is a matter of making others happy by meeting their expectations. On the pedestal, someone is elevated to a level of perfectionism that isn't realistic. Basically, it's ego playing out the role of being better than or less than.
Either way, the illusion of the hero will eventually be shattered. Any relationship built on falsehood, will not be sustainable.
Don't fill an empty void in you with fairy tales. See others for who they really are, then decide how you feel about them. And always be yourself so that you attract people who are genuine in their affection for you.
