This is a book full of wisdom and a book you can understand better if you have made enough mistakes while dealing with people.

The most important truth: Our human beings are craving for and desperately need the feeling of importance.

If you want to improve relationship with other people:
- Be interested in the other people

- Remembering their names

- Remembering their birthday

- Be thoughtful other people, willing to spend time to do things for other people

- Giving them they really want

- Be a good listener, encourage them to talk about themselves. People won’t listen to you while they’re still have a lot of ideas to get out.

- Ask questions the other people can and will enjoy answering.

- Be sympathetic, try to understand the other people.

- Avoid to embarrass your friends by making them feel inferior.

If you want to motivate the other people to do the things you want them to do:
- Don’t talk about what you want; tell them this is useful to them.

- Always make the other people happy about doing the things you suggest.

- Give suggestions instead of orders, let the other people think it’s their own choice.

- Letting the other people feel that the idea is his or hers.

- Give them a fine reputation to live up to. People want challenges, want to excel, to win.

If you want to criticize the other people:
- Do not discourage the other people by criticizing them. Praise them. “Hurting a man’s dignity is a crime!”

- Try to praise them every time when they made any progress.

- Get the other person’s point of view and see things from his or her angle, as well as from our own.

- Tell them you’ve made the same mistakes before and what you did to make sure not make those mistakes anymore

- Do not use “BUT”, use “AND”. “We’re really proud of you for raising your grades this term, AND by continuing the same conscientious efforts next term, your algebra grade can be up with all the others.”
