Do the right thing - This is the principle of integrity. George Marshall stood for the highest of values. In our lives this can be applied by clearly defining our mission statement, clearly defining the values we want to stand by and keeping our promises.
Master the situation – This is the principle of action. As a leader action is everything. Another key quality a leader needs is flexibility which is the ability to be nimble under the onslaught of change. Assess the situation and take appropriate action.
Serve the greater good – This is the principle of selflessness. Servant leadership is the best form of leadership. You have to find a mighty cause that serves a larger purpose than just profit. Business when it is combined with altruism is great for the world.
