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.
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.
