This concept struck such a collective chord in my book Positive Energy that in Emotional Freedom I illustrate how it applies to protecting your emotions and not absorbing other people's negativity. In the book I discuss these vampires to watch for and ways to deal with them.
I believe people have much to teach us and that we truly are equals. I was raised to believe that people, given the chance, can make something of themselves. But I do not value someone being wealthy or having stuff or having power as being successful.
It is easy to understand the reactions of those who respond to the emotional vampires in their lives with umbrage, anger, ridicule and pain. Those feelings are real, but in choosing to nurture them we imprison ourselves.
