A friend gave me a book to read called "The Four Agreements" by Don Miguel Ruiz. The Four Agreements are very simple, but very profound. Whether you are Christian, Jewish, Muslim or none of the above, these agreements are practical, down-to-earth guideposts for anyone seeking better relationships with those around them.
The Four Agreements are:
1. Be Impeccable With Your Words
2. Don't Take Anything Personally
3. Don't Make Assumptions
4. Always Do Your Best
These Four Agreements might seem overly simplified by themselves, but I found the book to be a powerful reminder of the effect your words and thoughts have on everything you do in life. With only 96 pages, it's a very quick read.
