The four ingredients to being a great leader (according to Margaret Thatcher):
First, know what matters to you. Have a set of principles and follow them. Your principles serve as the foundation of your leadership. Second, speak up! Be bold and fearless about asserting your principles. Third, anticipate problems. Use information, instinct, and intuition to foresee problems and crises before anyone else does. Fourth, make bold decisions. Base your decisions on your principles and on the information and insight that you have. Meet problems and opportunities head-on, then take bold action. Those are the four ingredients of a great leader.
