The Four Agreements
Miguel Ruiz (1989)
1. Be impeccable with your words
2. Don’t make assumptions
3. Don’t take things personally
4. Do the best you can
"There is nothing more dangerous than to build a society, with a large segment of people in that society, who feel that they have no stake in it; who feel that they have nothing to lose. People, who have a stake in their society, protect that society, but when they don't have it, they unconsciously want to destroy it."
