"Envy and resentment are terribly corrosive passions. To suffer at the sight or even the thought of others' enjoyment of life makes one a committed enemy of human happiness. Such people end up being practically a curse upon the human race. They vandalize life, exerting themselves not in the pursuit of gain or pleasure, but to hinder others' enjoyment."
