As an introvert, you can be your own best friend or your worst enemy. The good news is we generally like our own company, a quality that extroverts often envy. We find comfort in solitude and know how to soothe ourselves. Even our willingness to look at ourselves critically is often helpful.
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.
