Envy is one of the most harmful and dangerous feeling which people experience. It is so widespread in society that even a close friend can bear it against you. Why does it happen? Why can’t most people fight against it? I admit that there is hardly any person in the world who has never felt vexation, roused by someone else’s prosperity or success. There is always someone beside you who is better at studying, sports, or love, who is prettier, smarter, more confident, strong-willed or industrious. This list may be continued for ever and ever. Of course you will cut a poor figure against such a go –getter. It sounds rather depressing, but unfortunately it is the simple truth of our life.
