“ Any teacher can take a child to the classroom, but not every teacher can make him learn. He will not work joyously unless he feels that liberty is his, whether he is busy or at rest; he must feel the flush of victory and the heart-sinking of disappointment before he takes with a will the tasks distasteful to him and resolves to dance his way bravely through a dull routine of textbooks. ”
 Helen Keller, The Story of My Life (1903). copy citation
