Envy is a con man, a tugger at your sleeve, a knocker at your door. Let me in for just a moment, it says, for just one moment of your time. … The antidote to envy is one’s own work. Not the thinking about it. Not the assessing of it. But the doing of it. The answers you want can come only from the work itself. It drives the spooks away.
–Bonita Freedman, from Walking on Alligators, by Susan Shaughnessy.
And, I would add, envy kills your joy in your work, your work that none other can do.
