You envy me? What a wretch you must be to feel diminished in your sense of self-worth by comparison with me! I have something you lack? Why isn't that compensated for by what you have that I lack? You feel bad that I have achieved something by my hard work? Don't you realize that you waste time and energy that could be used to improve your own lot?
You ought to feel bad, not because I do well, but because you are so foolish as to indulge envy. Vices vitiate, they weaken. You weaken yourself and make yourself even more of a wretch by succumbing to envy.
