“When you treat your competitors with the courtesy and respect you would like, most will respond in kind, and the results is a stable, productive, profitable industry. On the other hand, an industry or market that is composed of vicious, unethical competitors will soon destroy itself. When you are asked how your products and services compare with those of you competitors, speak respectfully and politely about your rivals, but use the question to shift the discussion to your company and your products. Acknowledge others’ good points, and then move on. If you complain too much about the competition, prospective customers may wonder what they are missing and refuse to buy until they have compared your products and services with those of others.”
– Napoleon Hill
