Envy: a feeling of discontented or resentful longing aroused by someone else’s possessions, qualities, or luck.
Envy is the ugliest of the seven deadly sins. Envy stems from dissatisfaction and inferiority.
In Memoriam 16: I Envy Not In Any Moods by Alfred Tennyson
I envy not in any moods The captive void of noble rage, The linnet born within the cage, That never knew the summer woods:
I envy not the beast that takes His license in the field of time, Unfetter’d by the sense of crime, To whom a conscience never wakes;
Nor, what may count itself as blest, The heart that never plighted troth But stagnates in the weeds of sloth; Nor any want-begotten rest.
I hold it true, whate’er befall; I feel it, when I sorrow most; ’Tis better to have loved and lost Than never to have loved at all.
