Resentment is like taking poison and waiting for the other person to die. - Malachy McCourt
As you embrace the present and become one with it, and merge with it, you will experience a fire, a glow, a sparkle of ecstasy throbbing in every sentient being. As you begin to experience this exultation of spirit in everything that is alive, as you become intimate with it, joy will be born within you, and you will drop the terrible burdens of defensiveness, resentment, and hurtfulness... then you will become lighthearted, carefree, joyous, and free. - Deepak Chopra
It is impossible for you to be angry and laugh at the same time. Anger and laughter are mutually exclusive and you have the poser to choose either. - Whyne Dyer
Resentment seems to have been given us by nature for a defense, and for a defense only! It is the safeguard of justice and the security of innocence. - Adam Smith
I will not be alone if I am my true self. Only by trading my true self for the companionship of another have I ever made myself alone. Because when I gave up my real self, I wound up resenting my “significant other” for “making me” do that—and it was this resentment that ate away at our relationship. - Donald Walsch .
