"Envy is an emotion that "occurs when a person lacks another’s superior quality, achievement, or possession and either desires it or wishes that the other lacked it." At the core of envy seems to be an upward social comparison that threatens a person's self-esteem: another person has something that the envier considers to be important to have. If the other person is perceived to be similar to the envier, the aroused envy will be particularly intense, because it signals to the envier that it just as well could have been him or her who had the desired object."

“You can't be envious and happy at the same time”
(Frank Tyger)

I envy Seas, whereon He rides—
I envy Spokes of Wheels
Of Chariots, that Him convey—
I envy Crooked Hills
That gaze upon His journey—
How easy All can see
What is forbidden utterly
As Heaven—unto me!
I envy Nests of Sparrows—
That dot His distant Eaves—
The wealthy Fly, upon His Pane—
The happy—happy Leaves—
That just abroad His Window
Have Summer's leave to play—
The Ear Rings of Pizarro
Could not obtain for me—
I envy Light—that wakes Him—
And Bells—that boldly ring
To tell Him it is Noon, abroad—
Myself—be Noon to Him—
Yet interdict—my Blossom—
And abrogate—my Bee—
Lest Noon in Everlasting Night—
Drop Gabriel—and Me—
poem by Emily Dickinson
