The world is full of hundreds of beautiful things we can never possibly have time to discover, and there is no time to be unkind or envious or ungenerous, and no sense in enslaving the mind to the trivialities of the moment. For you can be equal to the greatness of life only by marching with it; not by seeking love but by giving it, nor seeking to be understood but learning to understand. And when it is all over, there will be an agony of remorse because one spared the effort and did not make more of that little span of opportunity; and knowing reality at last, who knows but that one will look back with unassuageable regret upon one's pitiful little faith.
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.
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.
