The most powerful concepts in personal development are often very simple, and easy to apply. Several examples of this can be found in Dale Carnegie’s classic book, How to Win Friends and Influence People. First published in 1937, this timeless classic is just as useful today as it was when it was first published.
Here are Dale Carnegie’s Six Ways to Make People Like You:
Principle 1. Become genuinely interested in other people.
Principle 2. Smile.
Principle 3. Remember that a person’s name is to that person the sweetest and most important sound in any language.
Principle 4. Be a good listener: Encourage others to talk about themselves.
Principle 5. Talk in terms of the other person’s interests.
Principle 6. Make the other person feel important – and do it sincerely.
