I'm not going to copy the entire piece from Matt's post, you can read that by clicking here; I will, however, excerpt this portion:
. . . there exists a kind of anxiety gap between what is and what we think should be. “I should have a PhD like Rob Wolcott.” “I deserve to be as wealthy as Ben Elowitz, because I was instrumental in building the Blue Nile business.” This is the drama of comparative living. Bertrand Russell, in The Conquest of Happiness, calls it “worry fatigue.” He says, “Envy is a form of vice which consists of seeing things never in themselves, but only in their relations.” He had a great example: “Napoleon envied Caesar; Caesar envied Alexander; Alexander I daresay envied Hercules, who didn’t exist.”Everyone should read the entire portion that Matt posted on his blog . . . . probably more than once.
I am fairly certain that the destructive emotion of envy has increased in the age in which we are living.
