The principles in the book are simple, but something a lot of us fail to use or remember. This book will help you to convince people to your way of thinking, avoid arguments and become more like. If you're in a leadership or sales type role, I strongly recommend this book.

This summary will discuss Carnegie’s 4 key concepts; each of these has a number of key principles we will summarise.

1. Fundamental techniques in handling people.
2. Ways to make people like you.
3. How to win people to your way of thinking.
4. How to change people without giving or arousing resentment.
