Jeanne d'Arc is known as the 15th century warrior who supported Charles VII during the war of 100 years against the English. She rallied the troops and lifted the siege of Orléans. As much as her military wins and her whole demeanor are admirable, I warn against exhausting oneself like Jeanne did. Change managers should strive to become a 2.0 version of her: strategic thinkers who remove themselves from the arena and ensure they stay centered.
