"Fear doesn't exist anywhere except in the mind"

This quote by Dale Carnegie recommends that fear is a psychological construct, and does not exist in the real world. Worry is a feeling that is produced in our minds, and is not an actual tangible thing. It is a reaction to a perceived hazard, and is a natural action to danger. Fear can be an effective feeling, and can cause us to act in manner ins which we would not generally act. However, it is necessary to bear in mind that fear is not real, which it is something that we can manage. We can choose to face our fears and take action, or we can choose to ignore them and stay in our comfort zone. By understanding that fear is a psychological construct, we can take control of our lives and make positive modifications.
