Close friends and relatives, while not meaning to do so, often handicap one through “opinions” and sometimes through ridicule, which is meant to be humorous. Thousands of men and women carry inferiority complexes with them all through life, because some well-meaning, but ignorant person destroyed their confidence through “opinions” and ridicule.
You have a brain and a mind of your own. Use it, and reach your own decisions. If you need facts or information from other people, to enable you to reach decisions, as you probably will in many instances; acquire these facts or secure the information you need quietly, without disclosing your purpose.
~ Napoleon Hill, Think & Grow Rich (1937)
