I get a monthly newsletter from Xavier University Men's Basketball program.
In one of the newsletters it included The Four Agreements by Don Miguel Ruiz. Found it interesting and a good guide in life.
1. Always Do Your Best: No matter the circumstance do your best, no more, no less. When doing your best, you will learn to accept yourself, you will learn from your mistakes, look honestly at results and keep working. You will be accountable to yourself and to others.
2. Be Impeccable with your Word: Your word is the power to express and communicate which creates events in your life. Take responsibility for your actions, but do not judge or blame yourself too harshly.
3. Don't Take Anything Personally: Taking things personally is the maximum expression of selfishness because we assume that everything is about me. Nothing other people do is because of you, it is because of them.
4. Don't Make Assumptions: You tend to make assumptions on everything and the problem is that we believe that assumption to be the truth. We assume things on what others are doing or thinking and we take it personally. To keep from doing this, ask questions until it is clear what it is that you want to know.
