"2. Don’t Take Anything Personally
Nothing others do is because of you. What others say and do is a projection of their own reality, their own dream. When you are immune to the opinions and actions of others, you won’t be the victim of needless suffering."
Some time back I was having fun with "Panoslydios" over on the fight forum. He/she was trying very hard to insult me and it did not work. I was actually amused. I learned long ago what someone thinks is me is none of my business.
Don Miguel Ruiz is saying something along this line. I do have his book "http://www.amazon.com/The-Four-Agreements-Practical-Personal/dp/1878424319"
