“Like hatred, jealousy is forbidden by the laws of life because it is essentially destructive.” ~ Alexis Carrel
“Jealousy is the fear of comparison.” ~ Max Frisch
“A competent and self-confident person is incapable of jealousy in anything. Jealousy is invariably a symptom of neurotic insecurity.” Robert A. Heinlein
