If you want to live your life, not someone else's life, want your needs to be met and relationships with people to develop, you must learn to set boundaries. Many neglect borders for fear that others will stop loving and accepting us if we draw the line. We are terribly afraid to annoy or upset others. We are afraid that we will be abandoned and we will be left alone. We believe that by taking care of ourselves, we act as selfish. That is why we sacrifice ourselves, supporting the "thin world": a false feeling of harmony. This book is about the fact that borders do not always lead to conflict. It is about the fact that you have the right to borders regardless of what others want from you, and these borders can run anywhere. You can compromise, you can arrange negotiations, but you should not abandon the most important principles. For those accustomed to pleasing, cozied up to the role of savior, benefactor and solver of other people's problems, the very thought of putting yourself first seems radical. But truth, close trust, freedom - all this will be revealed to you only when you put your desires first, discarding fears and doubts. After reading this book, you will learn how to do it.
