A great passage from Napoleon Hill’s “Grow Rich With Peace Of Mind.”
“It is obvious that those who are filled with malice and envy do not have peace of mind; their malice and envy sour their lives. Failure so often hates the very sight of success. Speaking with successful men, I have noticed they speak in complimentary terms of other men who are succeeding. Their attitude is not one of envy, but one of willingness to learn from others. The failure, on the other hand, goes out of his way to find some adverse criticism of the successful person. If he can’t find anything doubtful about the way that person does business, then he will pick at some other area. His malice is evident, and so it the sad fact that he not only cannot command what money can buy, but also he cannot attain peace of mind.”

BTW, the entire book, Grow Rich With Peace Of Mind, is highly recommended.
