Fear of failure is a prime cause of anxiety. People think, "If I don't succeed, I am a worthless failure."

Someone who fears failure is not willing to take the risks that are an essential ingredient in every new undertaking. This prevents him from taking action in many situations in which he could accomplish a great deal.

If someone accepts that his intrinsic worth as a person is never at risk ― even if he does not succeed at a given task ― then he is likely to try much more to accomplish.
