“Each of us has the ability to put our unique human potential into action and to acquire a desired result. But the one thing that determines the level of our potential, that produces the intensity of our activity, and that predicts the quality of the result we receive is our attitude.
Attitude determines how much of the future we are allowed to see. It decides the size of our dreams and influences our determination when we are faced with new challenges. No other person on earth has dominion over our attitude. People can affect our attitude by teaching us poor thinking habits or unintentionally misinforming us or providing us with negative sources of influences, but no one can control our attitude unless we voluntarily surrender control.
No one else “makes us angry.” We make ourselves angry when we surrender control of our attitude. What someone else may have done is irrelevant. We choose, not they. They merely put our attitude to the test. If we select a volatile attitude by becoming hostile, angry, jealous or suspicious, then we have failed the test. If we condemn ourselves by believing that we are unworthy, then again, we have failed the test.
If we care at all about ourselves, then we must accept full responsibility for our own feelings. We must learn to guard against those feelings that have the capacity to lead our attitude down the wrong path and to strengthen those feelings that can lead us confidently into a better future.” Jim Rohn, The Five Major Pieces of the Life Puzzle
