Leadership is the art of accomplishing more than the science of management says is possible. (Colin Powell, former US Secretary of State)
People who lead must understand their role. Whether a business executive, a labor manager, or a teacher, leaders must appreciate their responsibility to prepare and challenge their workers or learners. Leaders are managers, of course, but successful leaders are artists, too. Their handling of programs, people, and problems demands the finest of skills.
In your teaching show integrity, seriousness and soundness of speech that cannot be condemned (Titus 2:7, 8).
