Timeless advice from Napoleon Hill:
They permit the newspapers and gossiping neighbors to do their thinking for them. Opinions are the cheapest commodity on earth.
Everybody has a flock of opinions ready to be wished upon anyone who will accept them.
If you are influenced by opinions when you reach decisions you will not succeed in any undertaking, much less in transmuting your own desire into money.
If you are influenced by the opinions of others, you will have no desire of your own.
Keep your own counsel.
When you begin to make your own decisions, take no one into your confidence except members of your mastermind group. And be very sure in your selection of this group, that you choose only those who will be in complete harmony with your purpose.
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.
If you need facts or information from other people to enable your to reach decisions, as you probably will in many instances, acquire these facts quietly without disclosing your purpose.
You have a brain and a mind of your own. Use it. And reach your own decisions.
