There are people who are always late. And there are those who always arrive on time and get nervous when they are forced to wait. There are people who like to promise but not deliver. Others, on the contrary, try to keep their word and demand the same from others. One way or another, we suffer from delays and unfulfilled promises - our own or others', so the book by psychologist O. M. Krasnikova concerns absolutely everyone. After reading it, you will find out why it is so difficult for some people to arrive on time, and learn to minimize the damage from your own or someone else’s lack of obligation. The author also hopes that her book will help us better understand ourselves and others, and perhaps become a little more tolerant.
