God did not give us a spirit of timidity, but a spirit of power, of love and of self-discipline. (2 Timothy 1:7)

Be strong and courageous. Do not be terrified; do not be discouraged, for the LORD your God will be with you wherever you go. (Joshua 1:9)

“Courage is the willingness to risk. To lead is to act. To have courage is to take charge, first of one’s life, for the true hero is not the person who conquers others but the one who conquers himself or herself. Courage is the ability to exhibit personal autonomy and independence of thought, to take the initiative, to be a self-starter. Courage means that you are willing to stand alone. You define yourself. You invent who you are. You are responsible for who you are. Courage is the free decision to tolerate maximum amounts of anxiety, to manage your anxiety constructively, to understand that being anxious is what it feels like to grow. The courageous leader claims the power, at all times, to initiate, act, and risk. Courage means acting with sustained initiative.” (Peter Koestenbaum, Leadership: the inner side of greatness, a philosophy for leaders, 49-52)
