What is the life-changing difference of between being afraid and conquering fear?
Conquering fear begins by accepting that fear is part of human life. The most liberating insight is to recognize that fear is not the only factor in your mind. You can choose to "feel the fear and do it anyway" or you can stifle yourself to protect yourself from danger. The essential point is that you can be afraid and courageous at the same time.
How does courage relate to fear? Courage is not about lack of fear. Courageousness is a decision to act despite your fear. The essence of courage is to do what you choose to do, no matter how afraid you are.
Consider what Nelson Mandela said about courage and fear.
I learned that courage was not the absence of fear, but the triumph over it. The brave man is not he who does not feel afraid, but he who conquers that fear.
The critical word to ponder is conquer. What is most fascinating and empowering about the etymology of the word conquer are the definitions: "to search for, to procure by effort, to win." In other words, "to conquer" is to set out on a deliberate effort to overcome something.
