Changing the quality of thinking. The way you think and feel about yourself, including your beliefs and expectations about what is possible for you, determines everything you do and everything that happens to you.When you change the quality of your thinking, you change the quality of your life, sometimes instantly.

Positive thoughts are life enhancing. They empower you and make you feel stronger and more confident. Positive thinking is not just a motivational idea. It has measurable, constructive effects on your personality, your health, your levels of energy, and your creativity. The more positive and optimistic you are, the happier you will be in every area of your life.

Negative thoughts bring about the opposite. They disempower you and make you feel weaker and less confident. Whenever you think or say something negative, you give your power away. You feel angry and defensive. You feel frustrated and unhappy. Over time, negative thinking can make you physically ill, and even poison your relationships. Positive thinking leads to mental health and peak performance. Negative thinking leads to mental illness and decreased effectiveness. Your goal, therefore, if you want to live a wonderful life, is to cultivate positive emotions and get rid of negative emotions.

The elimination of negative emotions is the most important single step you can take toward health, happiness, and personal wellbeing. Each time you take complete control over your thoughts and feelings, and discipline yourself to keep them positive, the quality of both your inner and outer lives improves. In the absence of negative emotions, your mind automatically fills with the positive emotions that generate feelings of happiness and fulfillment.

''Your mind can hold only one thought at a time, positive or negative.You can substitute a positive thought for a negative thought whenever you choose.'' You can apply this law by deliberately thinking about something positive whenever you want to cancel out a thought or feeling that makes you angry or unhappy.

Your negative emotions have all been learned, beginning in childhood. And what has been learned can be unlearned, sometimes quite quickly.You can learn any habit or skill that you consider to be either desirable or necessary. Especially, you can learn positive, constructive ways of thinking about people, money, health, and other factors to cancel out negative ideas that limit your potential and interfere with your success.

Many negative ideas or attitudes are based on false premises. Sometimes a negative idea about a subject, or a negative attitude toward a person, can be completely reversed with a single piece of new information. You could suddenly learn that an idea you had about yourself or another person was not true. As a result, you could change your thinking in an instant. Be open to this possibility.

Justification is what you need.

Justification is what you do when you rationalize or create a reason for your anger and unhappiness.You tell yourself, and whoever else will listen, how badly you were treated and how dreadfully the other person behaved. You continually rehash the situation in your mind.You repeat all the reasons you have for being upset. Each time you think of the person or situation, you become angry.You feel entitled to your anger, as if you have paid a high price for it, especially since, in your estimation, you were such a good and virtuous person.
