The second agreement simply states: Don't take anything personally. In the book The Four Agreements, Don Miguel Ruiz explains: Whatever happens around you, don't take it personally… Nothing other people do is because of you. It is because of themselves. All people live in their own dream, in their own mind; they are in a completely different world from the one we live in. When we take something personally, we make the assumption that they know what is in our world, and we try to impose our world on their world.
