Courage is a characteristic and priceless virtue successful people often speak or write about.

Courage is not the absence of fear. Courageous people do feel fear, but they are able to manage and overcome their fear so that it does not stop them taking action.

According to Oliver Wendell Holmes, Courage is about doing what you’re afraid to do. There can be no courage unless you’re scared. Have the courage to act instead of react.

When we are afraid we ought not to occupy ourselves with endeavoring to prove that there is no danger, but in strengthening ourselves to go on in spite of the danger. (Mark Rutherford)
