The fear response is designed to keep you safe by flagging potentially threatening or risky situations. This is clearly an asset when it comes to self-preservation in life threatening and dangerous circumstances.
There are some instances, however, that result in the fear response misfiring. It activates in the face of an uncomfortable event, rather than a dangerous one.
Learn how to face your fears with the understanding that learning, growth, and personal development, by way of expanding your comfort zone, are on the other side.
Periods of discomfort are your friend; they help you grow. Constant comfort is a silent prison.
